Manual‐guided cognitive–behavioural therapy for insomnia delivered by ordinary primary care personnel in general medical practice: a randomized controlled effectiveness trial

Chronic insomnia is a prevalent problem in primary health care and tends to be more serious than insomnia in the general population. These patients often obtain little benefit from hypnotics, and are frequently open to exploring various options for medical treatment. However, most general practitioners (GPs) are unable to provide such options. Several meta‐analyses have shown that cognitive–behavioural therapy (CBT) for insomnia results in solid improvements on sleep parameters, and a few studies have demonstrated promising results for nurse‐administered CBT in primary care. The aim of this randomized controlled study was to investigate the clinical effectiveness of manual‐guided CBT for insomnia delivered by ordinary primary care personnel in general medical practice with unselected patients. Sixty‐six primary care patients with insomnia were randomized to CBT or a waiting‐list control group. The CBT group improved significantly more than the control group using the Insomnia Severity Index as the outcome. The effect size was high. Sleep diaries showed a significant, medium‐sized treatment effect for sleep onset latency and wake time after sleep onset. However, for all measures there is a marked deterioration at follow‐up assessments. Almost half of the treated subjects (47%) reported a clinically relevant treatment effect directly after treatment. It is concluded that this way of delivering treatment may be cost‐effective.     

Controlled‐release melatonin,singly and combined with cognitive behavioural therapy,for persistent insomnia in children with autism spectrum disorders: a randomized placebo‐controlled trial

Although melatonin and cognitive–behavioural therapy have shown efficacy in treating sleep disorders in children with autism spectrum disorders, little is known about their relative or combined efficacy. One hundred and sixty children with autism spectrum disorders, aged 4–10 years, suffering from sleep onset insomnia and impaired sleep maintenance, were assigned randomly to either (1) combination of controlled‐release melatonin and cognitive–behavioural therapy; (2) controlled‐release melatonin; (3) four sessions of cognitive–behavioural therapy; or (4) placebo drug treatment condition for 12 weeks in a 1 : 1 : 1 : 1 ratio. Children were studied at baseline and after 12 weeks of treatment. Treatment response was assessed with 1‐week actigraphic monitoring, sleep diary and sleep questionnaire. Main outcome measures, derived actigraphically, were sleep latency, total sleep time, wake after sleep onset and number of awakenings. The active treatment groups all resulted in improvements across all outcome measures, with moderate‐to‐large effect sizes from baseline to a 12‐week assessment. Melatonin treatment was mainly effective in reducing insomnia symptoms, while cognitive–behavioural therapy had a light positive impact mainly on sleep latency, suggesting that some behavioural aspects might play a role in determining initial insomnia. The combination treatment group showed a trend to outperform other active treatment groups, with fewer dropouts and a greater proportion of treatment responders achieving clinically significant changes (63.38% normative sleep efficiency criterion of >85% and 84.62%, sleep onset latency <30 min). This study demonstrates that adding behavioural intervention to melatonin treatment seems to result in a better treatment response, at least in the short term.     

Subjective–objective sleep discrepancy in patients with insomnia during and after cognitive behavioural therapy: An actigraphy study

Although patients with insomnia often show a discrepancy between self‐reported and objective sleep parameters, the role of and change in this phenomenon during treatment remain unclear. The present study aimed to assess the effect of cognitive behavioural therapy for insomnia on subjective and objective sleep discrepancy of total sleep time, sleep‐onset latency and wake after sleep onset. The total sleep time discrepancy was also assessed across the entire therapy. The second aim was to examine the treatment outcome of two insomnia groups differing in sleep perception. Thirty‐six adults with insomnia (mean age = 46.7 years, SD = 13.9; 22 females) were enrolled in the final analyses. Patients underwent a 6‐week group cognitive behavioural therapy for insomnia programme. Sleep diary and actigraphy measurements were obtained during the therapy. Patients who underestimated total sleep time (n = 16; underestimating group) were compared with patients who accurately perceived or overestimated total sleep time (n = 20; accurate/overestimating group). After cognitive behavioural therapy for insomnia, a significant decrease of total sleep time and sleep‐onset latency discrepancy was observed without a change in wake after sleep onset discrepancy in the total sample. Only the underestimating group reported decreased sleep‐onset latency discrepancy after the treatment, whereas total sleep time discrepancy significantly changed in both groups. The underestimating group showed a significant decrease of total sleep time discrepancy from Week 1 to Week 2 when the sleep restriction was implemented, whereas the accurate/overestimating group showed the first significant change at Week 4. In conclusion, both groups differing in sleep perception responded similarly to cognitive behavioural therapy for insomnia, although different In conclusion, both groups differing in sleep perception responded similarly to cognitive behavioural therapy for insomnia, although different therapeutic components could play important roles in each group. components could play important roles in each group.     

Self‐administered acupressure for insomnia disorder: a pilot randomized controlled trial

Self‐administered acupressure has potential as a low‐cost alternative treatment for insomnia. To evaluate the short‐term effects of self‐administered acupressure for alleviating insomnia, a pilot randomized controlled trial was conducted. Thirty‐one subjects (mean age: 53.2 years; 77.4% female) with insomnia disorder were recruited from a community. The participants were randomized to receive two lessons on either self‐administered acupressure or sleep hygiene education. The subjects in the self‐administered acupressure group (n = 15) were taught to practise self‐administered acupressure daily for 4 weeks. The subjects in the comparison group (n = 16) were advised to follow sleep hygiene education. The primary outcome was the Insomnia Severity Index (ISI). Other measures included a sleep diary, Hospital Anxiety and Depression Scale and Short‐form Six‐Dimension. The subjects in the self‐administered acupressure group had a significantly lower ISI score than the subjects in the sleep hygiene education group at week 8 (effect size = 0.56, P = 0.03). However, this observed group difference did not reach a statistically significant level after Bonferroni correction. With regard to the secondary outcomes, moderate between‐group effect sizes were observed in sleep onset latency and wake after sleep onset based on the sleep diary, although the differences were not significant. The adherence to self‐administered acupressure practice was satisfactory, with 92.3% of the subjects who completed the lessons still practising acupressure at week 8. In conclusion, self‐administered acupressure taught in a short training course may be a feasible approach to improve insomnia. Further fully powered confirmatory trials are warranted.     

Telehealth‐delivered CBT‐I programme enhanced by acceptance and commitment therapy for insomnia and hypnotic dependence: A pilot randomized controlled trial

Cognitive behavioural therapy for insomnia is the recommended treatment for chronic insomnia. However, up to a quarter of patients dropout from cognitive behavioural therapy for insomnia programmes. Acceptance, mindfulness and values‐based actions may constitute complementary therapeutic tools to cognitive behavioural therapy for insomnia. The current study sought to evaluate the efficacy of a remotely delivered programme combining the main components of cognitive behavioural therapy for insomnia (sleep restriction and stimulus control) with the third‐wave cognitive behavioural therapy acceptance and commitment therapy in adults with chronic insomnia and hypnotic dependence on insomnia symptoms and quality of life. Thirty‐two participants were enrolled in a pilot randomized controlled trial: half of them were assigned to a 3‐month waiting list before receiving the four “acceptance and commitment therapy‐enhanced cognitive behavioural therapy for insomnia” treatment sessions using videoconference. The primary outcome was sleep quality as measured by the Insomnia Severity Index and the Pittsburgh Sleep Quality Index. All participants also filled out questionnaires about quality of life, use of hypnotics, depression and anxiety, acceptance, mindfulness, thought suppression, as well as a sleep diary at baseline, post‐treatment and 6‐month follow‐up. A large effect size was found for Insomnia Severity Index and Pittsburgh Sleep Quality Index, but also daytime improvements, with increased quality of life and acceptance at post‐treatment endpoint in acceptance and commitment therapy‐enhanced cognitive behavioural therapy for insomnia participants. Improvement in Insomnia Severity Index and Pittsburgh Sleep Quality Index was maintained at the 6‐month follow‐up. Wait‐list participants increased their use of hypnotics, whereas acceptance and commitment therapy‐enhanced cognitive behavioural therapy for insomnia participants evidenced reduced use of them. This pilot study suggests that web‐based cognitive behavioural therapy for insomnia incorporating acceptance and commitment therapy processes may be an efficient option to treat chronic insomnia and hypnotic dependence.     

Prevalence and management of chronic insomnia in Swiss primary care: Cross‐sectional data from the “Sentinella” practice‐based research network

We investigated the prevalence and treatment of patients with chronic insomnia presenting to Swiss primary care physicians (PCPs) part of “Sentinella”, a nationwide practice‐based research network. Each PCP consecutively asked 40 patients if they had sleep complaints, documented frequency, duration, comorbidities, and reported ongoing treatment. We analysed data of 63% (83/132) of the PCPs invited. The PCPs asked 76% (2,432/3,216) of included patients about their sleep (51% female); 31% (761/2,432) of these had had insomnia symptoms; 36% (875/2,432) had current insomnia symptoms; 11% (269/2,432) met the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM‐5) criteria for chronic insomnia (61% female). In all, 75% (201/269) of patients with chronic insomnia had comorbidities, with 49% (99/201) reporting depression. Chronic insomnia was treated in 78% (209/269); 70% (188/268) took medication, 38% (102/268) benzodiazepines or benzodiazepine receptor agonists, 32% (86/268) took antidepressants. Only 1% (three of 268) had been treated with cognitive behavioural therapy for insomnia (CBT‐I). A third of patients presenting for a non‐urgent visit in Swiss primary care reported insomnia symptoms and 11% met the DSM‐5 criteria for chronic insomnia. Hypnotics were the most common treatment, but almost no patients received first‐line CBT‐I. Reducing the burden of insomnia depends on disseminating knowledge about and access to CBT‐I, and encouraging PCPs to discuss it with and offer it as a first‐line treatment to patients with chronic insomnia.     

Subjective–objective sleep discrepancy among older adults: associations with insomnia diagnosis and insomnia treatment

Discrepancy between subjective and objective measures of sleep is associated with insomnia and increasing age. Cognitive behavioural therapy for insomnia improves sleep quality and decreases subjective–objective sleep discrepancy. This study describes differences between older adults with insomnia and controls in sleep discrepancy, and tests the hypothesis that reduced sleep discrepancy following cognitive behavioural therapy for insomnia correlates with the magnitude of symptom improvement reported by older adults with insomnia. Participants were 63 adults >60 years of age with insomnia, and 51 controls. At baseline, participants completed sleep diaries for 7 days while wearing wrist actigraphs. After receiving cognitive behavioural therapy for insomnia, insomnia patients repeated this sleep assessment. Sleep discrepancy variables were calculated by subtracting actigraphic sleep onset latency and wake after sleep onset from respective self‐reported estimates, pre‐ and post‐treatment. Mean level and night‐to‐night variability in sleep discrepancy were investigated. Baseline sleep discrepancies were compared between groups. Pre–post‐treatment changes in Insomnia Severity Index score and sleep discrepancy variables were investigated within older adults with insomnia. Sleep discrepancy was significantly greater and more variable across nights in older adults with insomnia than controls, P ≤ 0.001 for all. Treatment with cognitive behavioural therapy for insomnia was associated with significant reduction in the Insomnia Severity Index score that correlated with changes in mean level and night‐to‐night variability in wake after sleep onset discrepancy, P < 0.001 for all. Study of sleep discrepancy patterns may guide more targeted treatments for late‐life insomnia.     

CBT for late‐life insomnia and the accuracy of sleep and wake perceptions: Results from a randomized‐controlled trial

Subjective and objective estimates of sleep are often discordant among individuals with insomnia who typically under‐report sleep time and over‐report wake time at night. This study examined the impact and durability of cognitive‐behavioural therapy for insomnia on improving the accuracy of sleep and wake perceptions in older adults, and tested whether changes in sleep quality were related to changes in the accuracy of sleep/wake perceptions. One‐hundred and fifty‐nine older veterans (97% male, mean age 72.2 years) who met diagnostic criteria for insomnia disorder were randomized to: (1) cognitive‐behavioural therapy for insomnia (n = 106); or (2) attention control (n = 53). Assessments were conducted at baseline, post‐treatment, 6‐months and 12‐months follow‐up. Sleep measures included objective (via wrist actigraphy) and subjective (via self‐report diary) total sleep time and total wake time, along with Pittsburgh Sleep Quality Index score. Discrepancy was computed as the difference between objective and subjective estimates of wake and sleep. Minutes of discrepancy were compared between groups across time, as were the relationships between Pittsburgh Sleep Quality Index scores and subsequent changes in discrepancy. Compared with controls, participants randomized to cognitive‐behavioural therapy for insomnia became more accurate (i.e. minutes discrepancy was reduced) in their perceptions of sleep/wake at post‐treatment, 6‐months and 12‐months follow‐up (p < .05). Improved Pittsburgh Sleep Quality Index scores at each study assessment preceded and predicted reduced discrepancy at the next study assessment (p < .05). Cognitive‐behavioural therapy for insomnia reduces sleep/wake discrepancy among older adults with insomnia. The reductions may be driven by improvements in sleep quality. Improving sleep quality appears to be a viable path to improving sleep perception and may contribute to the underlying effectiveness of cognitive‐behavioural therapy for insomnia.     

Preventing sleep deficit in adolescents: Long‐term effects of a quasi‐experimental school‐based intervention study

Adolescents are at risk of sleep deficit, which has serious consequences for their daytime functioning. However, school‐based interventions to improve sleep have shown limited success. This might be due to the content of the programmes (e.g., not targeting central factors such as daytime stress and technology use) or because changes have not been captured due to a lack of long‐term follow‐ups. Hence, the aim of this study was to evaluate the long‐term effects of a school‐based sleep education curriculum including time‐management training. The study used a quasi‐experimental design. Participants were 3,622 adolescents (mean age 13.7, 48% girls); 286 were in the intervention group and 3,336 were followed as a natural control group. Data were collected before the intervention and at a 1‐year follow‐up. We divided participants into three groups according to baseline sleep duration (calculated from self‐reported bed‐ and wake times, minus sleep onset latency): insufficient (<7 hr), borderline (7–8 hr) and adequate (>8 hr). Adolescents in the intervention group were ~2 times less likely to report insufficient sleep at follow‐up as compared to controls. Sleep knowledge improved significantly in the intervention group but there were no changes in emotional sleep hygiene (e.g., bedtime worry) and perceived stress. Surprisingly, technology use increased and behavioural sleep hygiene worsened in the intervention group. Although the mechanisms of change need further investigation, the results of this study point to potential long‐term benefits of school‐based sleep programmes.     

Validity,potential clinical utility and comparison of a consumer activity tracker and a research‐grade activity tracker in insomnia disorder II: Outside the laboratory

Accurate assessment of sleep can be fundamental for monitoring, managing and evaluating treatment outcomes within diseases. A proliferation of consumer activity trackers gives easy access to objective sleep. We evaluated the performance of a commercial device (Fitbit Alta HR) relative to a research‐grade actigraph (Actiwatch Spectrum Pro) in measuring sleep before and after a cognitive behavioural intervention in insomnia disorder. Twenty‐five individuals with DSM‐5 insomnia disorder (M = 50.6 ± 15.9 years) wore Fitbit and Actiwatch and completed a sleep diary during an in‐laboratory polysomnogram, and for 1 week preceding and following seven weekly sessions of cognitive‐behavioural intervention for insomnia. Device performance was compared for sleep outcomes (total sleep time, sleep latency, sleep efficiency and wake after sleep onset). The analyses assessed (a) agreement between devices across days and pre‐ to post‐treatment, and (b) whether pre‐ to post‐treatment changes in sleep assessed by devices correlated with clinical measures of change. Devices generally did not significantly differ from each other on sleep variable estimates, either night to night, in response to sleep manipulation (pre‐ to post‐treatment) or in response to changes in environment (in the laboratory versus at home). Change in sleep measures across time from each device showed some correlation with common clinical measures of change in insomnia, but not insomnia diagnosis as a categorical variable. Overall, the Fitbit provides similar estimates of sleep outside the laboratory to a research grade actigraph. Despite the similarity between Fitbit and Actiwatch performance, the use of consumer technology is still in its infancy and caution should be taken in its interpretation.     

A randomized controlled trial of bedtime music for insomnia disorder

Music is often used as a self‐help tool to alleviate insomnia. To evaluate the effect of bedtime music listening as a strategy for improving insomnia, we conducted an assessor‐blinded randomized controlled trial. Fifty‐seven persons with insomnia disorder were included and randomized to music intervention (n = 19), audiobook control (n = 19) or a waitlist control group (n = 19). The primary outcome measure was the Insomnia Severity Index. In addition, we used polysomnography and actigraphy to evaluate objective measures of sleep, and assessed sleep quality and quality of life. The results showed no clear effect of music on insomnia symptoms as the group × time interaction only approached significance (effect size = 0.71, p = .06), though there was a significant improvement in insomnia severity within the music group. With regard to the secondary outcomes, we found a significant effect of the music intervention on perceived sleep improvement and quality of life, but no changes in the objective measures of sleep. In conclusion, music listening at bedtime appears to have a positive impact on sleep perception and quality of life, but no clear effect on insomnia severity. Music is safe and easy to administer, but further research is needed to assess the effect of music on different insomnia subtypes, and as an adjunctive or preventive intervention.     

Insomnia as a mediating therapeutic target for depressive symptoms: A sub‐analysis of participant data from two large randomized controlled trials of a digital sleep intervention

Insomnia predicts the onset of depression, commonly co‐presents with depression and often persists following depression remission. However, these conditions can be challenging to treat concurrently using depression‐specific therapies. Cognitive behavioural therapy for insomnia may be an appropriate treatment to improve both insomnia and depressive symptoms. We examined the effects of a fully‐automated digital cognitive behavioural therapy intervention for insomnia (Sleepio) on insomnia and depressive symptoms, and the mediating role of sleep improvement on depressive symptoms in participants from two randomized controlled trials of digital cognitive behavioural therapy for insomnia. We also explored potential moderators of intervention effects. All participants met criteria for probable insomnia disorder and had clinically significant depressive symptomatology (PHQ‐9 ≥ 10; n = 3,352). Individuals allocated to treatment in both trials were provided access to digital cognitive behavioural therapy. Digital cognitive behavioural therapy significantly improved insomnia (p < .001; g = 0.76) and depressive symptoms (p < .001; g = 0.48) at post‐intervention (weeks 8–10), and increased the odds (OR = 2.9; 95% CI = 2.34, 3.65) of clinically significant improvement in depressive symptoms (PHQ‐9 < 10). Improvements in insomnia symptoms at mid‐intervention mediated 87% of the effects on depressive symptoms at post‐intervention. No variables moderated effectiveness outcomes, suggesting generalizability of these findings. Our results suggest that effects of digital cognitive behavioural therapy for insomnia extend to depressive symptoms in those with clinically significant depressive symptomatology. Insomnia may, therefore, be an important therapeutic target to assist management of depressive symptoms.     

Internight sleep variability: its clinical significance and responsiveness to treatment in primary and comorbid insomnia

Although sleep diary and actigraphy data are usually collected daily for 1 or 2 weeks, traditional analytical approaches aggregate these data into mean values. Internight variability of sleep often accompanies insomnia. However, few studies have explored the relevance of this ‘construct’ in the context of diagnosis, clinical impact, treatment effects and/or whether having ‘variable sleep’ carries any prognostic significance. We explored these questions by conducting secondary analyses of data from a randomized clinical trial. The sample included primary (PI: n = 40) and comorbid insomnia (CMI: n = 41) sufferers receiving four biweekly sessions of cognitive–behavioural therapy (CBT) or sleep hygiene education. Using the within‐subject standard deviations of diary‐ and actigraphy‐derived measures collected for 2‐week periods [sleep onset latency (SOL), wake after sleep onset (WASO), total sleep time (TST) and sleep efficiency (SE)], we found that CMI sufferers displayed more variable self‐reported SOLs and SEs than PI sufferers. However, higher variability in diary and actigraphy‐derived measures was related to poorer sleep quality only within the PI group, as measured by the Pittsburgh Sleep Quality Index (PSQI). Within both groups, the variability of diary‐derived measures was reduced after CBT, but the variability of actigraphy‐derived measures remained unchanged. Interestingly, the variability of actigraphy measures at baseline was correlated with PSQI scores at 6‐month follow‐up. Higher SOL variability was associated with worse treatment outcomes within the PI group, whereas higher WASO variability was correlated with better treatment outcomes within the CMI group. Sleep variability differences across insomnia diagnoses, along with their distinctive correlates, suggest that mechanisms underlying the sleep disruption/complaint and treatment response in both patient groups are distinct. Further studies are warranted to support variability as a useful metric in insomnia studies.     

Sleep patterns and insomnia among adolescents: a population‐based study

The aim of the current study was to examine sleep patterns and rates of insomnia in a population‐based study of adolescents aged 16–19 years. Gender differences in sleep patterns and insomnia, as well as a comparison of insomnia rates according to DSM‐IV, DSM‐V and quantitative criteria for insomnia (Behav. Res. Ther., 41 , 2003, 427), were explored. We used a large population‐based study in Hordaland county in Norway, conducted in 2012. The sample included 10 220 adolescents aged 16–18 years (54% girls). Self‐reported sleep measurements included bedtime, rise time, time in bed, sleep duration, sleep efficiency, sleep onset latency, wake after sleep onset, rate and frequency and duration of difficulties initiating and maintaining sleep and rate and frequency of tiredness and sleepiness. The adolescents reported short sleep duration on weekdays (mean 6:25 hours), resulting in a sleep deficiency of about 2 h. A majority of the adolescents (65%) reported sleep onset latency exceeding 30 min. Girls reported longer sleep onset latency and a higher rate of insomnia than boys, while boys reported later bedtimes and a larger weekday–weekend discrepancy on several sleep parameters. Insomnia prevalence rates ranged from a total prevalence of 23.8 (DSM‐IV criteria), 18.5 (DSM‐V criteria) and 13.6% (quantitative criteria for insomnia). We conclude that short sleep duration, long sleep onset latency and insomnia were prevalent in adolescents. This warrants attention as a public health concern in this age group.     

Attentional bias towards sleep‐related stimuli in insomnia disorder: a behavioural and ERP study

Many studies have used behavioural experiments to show an attentional bias towards sleep‐related stimuli in people with insomnia disorder. A measurement of event‐related potential is needed to investigate the cognitive processing mechanism of the attentional process. The present study used the emotional Stroop paradigm and event‐related potentials to measure attentional bias towards sleep‐negative, sleep‐positive and sleep‐unrelated neutral words. The study comprised 16 participants with insomnia disorder and 15 participants who were good sleepers. Behavioural data indicated that there was a significant interference effect of sleep‐positive words between the insomnia group and the good sleepers, and a marginally significant interference effect from sleep‐negative words between groups. In the insomnia group, event‐related potential data showed that sleep‐negative words elicited higher amplitudes of P1 and N1 components than did sleep‐positive and sleep‐unrelated words. Our results provide evidence for the early cognitive processing of sleep‐negative stimuli, which suggests that the psychological treatment of insomnia could benefit from addressing early hypervigilance towards these stimuli.     

Randomized clinical effectiveness trial of nurse-administered small-group cognitive behavior therapy for persistent insomnia in general practice

STUDY OBJECTIVES: Persistent insomnia, although very common in general practice, often proves problematic to manage. This study investigates the clinical effectiveness and the feasibility of applying cognitive behavior therapy (CBT) methods for insomnia in primary care. DESIGN: Pragmatic randomized controlled trial of CBT versus treatment as usual. SETTING: General medical practice. PARTICIPANTS: Two hundred one adults (mean age, 54 years) randomly assigned to receive CBT (n = 107; 72 women) or treatment as usual (n = 94; 65 women). INTERVENTION: CBT comprised 5 sessions delivered in small groups by primary care nurses. Treatment as usual comprised usual care from general practitioners. MEASUREMENTS AND RESULTS: Assessments were completed at baseline, after treatment, and at 6-month follow-up visits. Sleep outcomes were appraised by sleep diary, actigraphy, and clinical endpoint. CBT was associated with improvements in self-reported sleep latency, wakefulness after sleep onset, and sleep efficiency. Improvements were partly sustained at follow-up. Effect sizes were moderate for the index variable of sleep efficiency. Participants receiving treatment as usual did not improve. Actigraphically estimated sleep improved modestly after CBT, relative to no change in treatment as usual. CBT was also associated with significant positive changes in mental health and energy/vitality. Comorbid physical and mental health difficulties did not impair sleep improvement following CBT. CONCLUSION: This study suggests that trained and supervised nurses can effectively deliver CBT for insomnia in routine general medical practice. Treatment response to small-group service delivery was encouraging, although effect sizes were smaller than those obtained in efficacy studies. Further research is required to consider the possibility that CBT could become the treatment of first choice for persistent insomnia in primary healthcare.     

Sustaining self‐regulatory efficacy and psychological outcome expectations for postnatal exercise: Effects of a group‐mediated cognitive behavioural intervention

Objective . The objective of the current investigation was to examine if the effects of a group‐mediated cognitive behavioural counselling plus exercise intervention were superior to the effects of a standard exercise care condition on postnatal mothers' self‐regulatory efficacy (SRE), outcome expectations (OEs) and self‐directed physical activity (PA). Design . The design of the study consisted of two intervention conditions; group‐mediated cognitive behavioural counselling plus exercise (GMCB) and standard exercise (SE). Each condition consisted of two phases; a 4‐week supervised, centre‐based intensive exercise training phase followed by a 4‐week home‐based phase. Methods . Participants were 57 postnatal women randomly assigned to conditions (SE: N = 31; GMCB: N = 26). Measures of SRE and OEs were assessed prior to and following the centre‐based aspect of the intervention. Physical activity was measured following the intensive exercise training phase as well as the home‐based phase. Results . GMCB participants' SRE and OEs were sustained during the intervention whereas those of SE participants declined. GMCB participants also reported significantly greater time spent engaging in self‐directed PA at the conclusion of the intensive and home‐based phases. Mediation analysis revealed that SRE partially mediated the relationship between intervention condition and post home‐based PA as confirmed by a significant sobel test. Conclusions . These findings suggest that a theory‐based GMCB counselling plus exercise intervention is superior to the SE condition in sustaining SRE and OEs, and in promoting greater self‐directed PA. SRE partially mediated the relationship between intervention condition and post home‐based PA supporting the targeting of that variable for change as part of the intervention.     

Clinical practice guidelines based on evidence for cognitive‐behavioural therapy in Parkinson's disease comorbidities: A literature review

The purpose of this review is to provide psychologists and other health care professional enough knowledge about available cognitive‐behavioural interventions for comorbidities in Parkinson's disease that include depression, anxiety, impulsive disorder, pain, and sleep disturbances. This review has clear clinical practical suggestions how to adapt psychological interventions and techniques to the motor and/or cognitive impairments of patients with Parkinson's disease, based on earlier available research results. Every available research that could be found with the help of search engines from Medline, Springer, PsychINFO, and Google Scholar, which used cognitive‐behavioural therapy to treat Parkinson's comorbidities, was cited and explained. Cognitive‐behavioural interventions and techniques are presented based on available research results for Parkinson's comorbidities. It is recommended to use treatment plans and interventions that are earlier suggested as efficient in patients with Parkinson's disease. Strongest available research based recommendations are available for depression and anxiety. There are only few available research studies that used cognitive and/or behavioural interventions for pain, impulsive disorder, or sleeping disturbances, except insomnia in Parkinson's disease. Cognitive‐behavioural therapy is safe to use and should be adapted to the specific needs of patients and with the scientific approved treatment interventions and techniques. Psychologists should be careful on how they adapt their treatment plan for patients.     

Effects of a tailored lifestyle self‐management intervention in patients with Type 2 diabetes

Objectives: The aim of the present study was to develop, implement and evaluate a brief intervention to improve adherence to the recommended lifestyle changes for patients with Type 2 diabetes, in particular to help patients to reduce the total amount of fat consumed and to increase lifestyle physical activity levels. Design and method: A brief, tailored lifestyle self‐management intervention for patients with Type 2 diabetes was evaluated in a randomized controlled trial. One hundred participants (aged 40 — 70 yrs) completed assessments at three time points— baseline, three months and one year. Participants were allocated to either an intervention group who received the brief tailored intervention including follow‐up telephone calls, or a usual care control group. Results: Results indicate that the intervention was successful in helping patients to reduce fat intake and, to a lesser extent, increase lifestyle physical activity levels. These self‐reported changes in behaviour were reflected in the objective data with weight maintenance in the intervention group compared to the control group, together with a significant reduction (2 cm) in waist circumference. Conclusions: These results provide further evidence of the effectiveness of tailored interventions for lifestyle change.
