Perfectionists' appraisal of daily hassles and chronic headache

OBJECTIVE: To investigate the relationships between daily hassles, perfectionism, and the experience of chronic headache among university students. BACKGROUND: Headaches are very common among university students. It has been found that a higher number of hassles reported by students is associated with an increase in headache activity. It has also been suggested that individuals higher in perfectionism appraise more situations as hassles, and that this dispositional characteristic may constitute a risk factor for the experience of chronic headaches. METHODS: A total of 291 university students completed three questionnaires: (1) the Headache Assessment Questionnaire that was utilized to obtain information on headache occurrence and its features, (2) the Brief College Student Hassles Scale, and (3) the Multidimensional Perfectionism Scale. RESULTS: A total of 18 students (6.2%) met the 2004 IHS criteria for chronic headaches, 179 (61.5%) met the criteria for frequent headaches, and 69 (23.7%) met the criteria for infrequent headaches. Students with chronic headaches reported significantly more stress, as measured by daily hassles. They also exhibited higher levels of perfectionism. The number of hassles reported was a significant predictor of headache frequency, intensity, and duration. Analyses also revealed that perfectionism was a significant predictor of headache frequency and intensity. CONCLUSIONS: The present study indicates that there is a relationship between perfectionism and chronic headache in university students, with those higher in perfectionism experiencing more frequent headaches. This investigation confirmed the relationship between daily hassles and chronic headache in this population. The results also suggest that perfectionists may generate their own stress through their tendency to appraise more situations as hassles. This, in turn, may explain their tendency to experience chronic headaches.     

The role of stressful life events in the persistence of primary headache: major events vs. daily hassles.

This study investigated the role of major stressful life events vs. minor life events (i.e., daily hassles) in the persistence of primary headache. It was hypothesized that chronic headache patients (n = 83) would be characterized not so much by exposure to a continued surfeit of inherently major life events as by a tendency to appraise cognitively and emotionally any ongoing microstressor or daily hassle as being more arousing or impactful than headache-free controls (n = 51). As predicted, chronic headache patients reported a significantly higher frequency (P < 0.01) and density (P < 0.01) of daily hassles, but not of major life events, than controls. Furthermore, minor life events were significantly correlated with headache frequency (P < 0.001) and density (P < 0.001) but not with gender, age and headache history. In terms of item content, health-related hassles (e.g., trouble relaxing) were perceived as being the most stressful. Significant differences between headache subgroups (chronic tension-type headache, migraine, mixed headache) were found, with tension-type and mixed headache sufferers reporting a higher incidence and density of daily hassles than migrainous patients. It was concluded that daily hassles were significantly associated with the persistence of headache and might be a better life event approach to chronic headache than major stressful events.     

Minor Stressful Life Events (Daily Hassles) in Chronic Primary Headache: Relationship with MMPI Personality Patterns

SYNOPSIS
This study investigated the relationship between minor life events ( i .e. daily hassles) and personality patterns from selected scales of MMPI in the persistence of primary headache in 83 patients. Comparisons between headache subgroups indicated that tension-type headache patients are much more likely than those with migraine to have experienced high level of microstress (hassles density),with mixed headache in between. Tension-type headache patients reported higher MMPI scores on scales 1, Hypochondriasis (somatic concern), scale 3, Hysteria (denial) and scale 7, Psychasthenia (anxiety), but not on scale 2 (Depression), than migrainous patients. In addition, individuals with high level of microstress appeared to be more depressed and anxious than low-stress headache patients, scoring significantly higher on MMPI scales 2 (Depression) and 7 (Psychasthenia). As no significant differences due to sex, age, headache history and status, except for the headache density ( i .e. severity x frequency) appeared, it is likely that high-stress levels are due, at least in part, to greater density of pain, rather than to discrete headache syndromes.
Our findings support the notion that depressed mood and anxiety may account for a third intervening variable in the relationship between chronic headache and life stress.     

The Role of Stress in Recurrent Tension Headache

SYNOPSIS
This study investigated the role of stress in recurrent tension headache. Although recurrent tension headache sufferers (N=117) and matched headache-free controls (N=174) reported similar numbers and types of stressful life events, headache sufferers reported a greater number of chronic everyday stresses or daily hassles than did controls . Recurrent tension headache sufferers also appraised the stressful events they experienced more negatively than did controls, and employed less effective coping strategies in their efforts to manage stressful events. When the potential impact of a stressful event was ambiguous, recurrent headache sufferers appraised this event more negatively and themselves as having less control over the event than did headache-free controls. In their coping efforts, recurrent tension headache sufferers also placed greater reliance on the relatively ineffective coping strategies of avoidance and self-blame, and made less use of social support than did controls. These findings suggest that research on the role of stress in tension headaches should focus not on the occurrence of major stressful life events, but on the recurrent headache sufferer's cognitive appraisals of stressful events and efforts to cope with stress.     

Interaction between anxiety, depression, quality of life and clinical parameters in chronic tension-type headache

Our aim was to investigate the mediating or moderating role of anxiety and depression in the relationship between headache clinical parameters and quality of life in Chronic Tension-Type Headache (CTTH). Twenty-five patients diagnosed with CTTH according to the criteria of the International Headache Society were studied. A headache diary was kept for 4 weeks in order to substantiate the diagnosis and record the pain history. Quality of life was assessed by means of the Medical Outcome Study (MOS) 36-Item Short-Form (SF-36) questionnaire. The Beck Depression Inventory (BDI-II) was used to assess depression, and the Trait Anxiety Scale (TA) from the State-Trait Anxiety Inventory was administered in order to assess anxiety. Moderating and mediating analyses were conducted with ordinary least squares multiple regression analysis using the SPSS General Linear Model procedure. Anxiety mediated the effect between headache frequency and quality of life, but not the effect of either headache intensity or duration. Anxiety totally mediated the effects of headache frequency on vitality, social functioning and mental health. On the other hand, depression modulated the effect in the mental health domain. The effect in the mental health domain was a function of the interaction between headache duration and depression (β = −0.34, p < 0.05), after controlling for age, gender, the main effects of headache duration, and depression. We did not find anxiety to be a moderating factor between intensity, frequency or duration of headache and perceived quality of life. Anxiety exerts a mediating effect, conditioning the relationship between headache frequency and some quality of life domains; depression seems to play an inherent role in the reduced quality of life of these patients, that is, it has a moderating effect.     

Impact of headache on quality of life in a general population survey in France (GRIM2000 Study)

OBJECTIVES: The objectives of this study were to determine the impact of headache on health-related quality of life in a nationwide sample of the French general population using a disease-specific measure, the Qualité de Vie et Migraine (QVM), to compare quality of life in subjects reporting different headache to types, and to evaluate the relationship between quality of life and severity, frequency, associated disability, and treatment responsiveness of headaches. METHODS: The QVM questionnaire was included within a large epidemiological survey of 1486 headache sufferers. Diagnosis was assigned retrospectively using an algorithm based on the International Headache Society classification. Headache severity was assessed with the MIGSEV scale and disability with the MIDAS scale. RESULTS: The mean global QVM score in the sample was 80.2. Quality of life was poorer in subjects with chronic daily headache (QVM score: 66.2) than in those with migraine (QVM score: 76.7), while those with other forms of episodic headache had the best quality of life (QVM score: 91.7). Quality-of-life scores were correlated with frequency, severity, disability, and treatment resistance of headaches (P <.001). CONCLUSION: The QVM scale is a sensitive tool to measure health-related quality of life in headache sufferers in the general population.     

Das Fibromyalgiesyndrom — eine somatoforme (Schmerz)störung?

The hypothesis that fibromyalgia (FM) should be classified as a somatoform disorder was assessed by reviewing current clinical studies. According to the ICD-10, somatic illness beliefs of the patient, high health care utilization, and frustrating patient-doctor relationships are diagnostic criteria of somatoform disorders. For the diagnosis of a somatoform pain disorder, a temporal association between the manifestation of pain and emotional or psychosocial conflicts and the exclusion of a depressive disorder are additionally required. Empirical studies demonstrate a higher lifetime and current prevalence of psychiatric disorders, childhood adversities, life events, and daily hassles and a higher health care utilization of FM patients. Studies also reveal that most patients believe that both somatic and psychosocial factors have caused their disorder. The patient-doctor relationship is characterized to be disappointing for both. Yet in all studies there were patients who did not fulfill the ICD-10 criteria of a somatoform (pain) disorder. A biopsychosocial model of FM differentiating between biological as well as psychosocial predisposing, triggering, and perpetuating factors in the pathogenesis of FM is presented as an alternative model. Hopefully the biopsychosocial model and the distinction of subgroups will enable more differentiated and tailored psychotherapeutic and pharmacological treatment strategies.     

The sensitivity to change of the cluster headache quality of life scale assessed before and after deep brain stimulation of the ventral tegmental area

BackgroundCluster headache (CH) is a trigeminal autonomic cephalalgia (TAC) characterized by a highly disabling headache that negatively impacts quality of life and causes limitations in daily functioning as well as social functioning and family life. Since specific measures to assess the quality of life (QoL) in TACs are lacking, we recently developed and validated the cluster headache quality of life scale (CH-QoL). The sensitivity of CH-QoL to change after a medical intervention has not been evaluated yet.MethodsThis study aimed to test the sensitivity to change of the CH-QoL in CH. Specifically we aimed to (i) assess the sensitivity of CH-QoL to change before and following deep brain stimulation of the ventral tegmental area (VTA-DBS), (ii) evaluate the relationship of changes on CH-QoL with changes in other generic measures of quality of life, as well as indices of mood and pain. Ten consecutive CH patients completed the CH-QoL and underwent neuropsychological assessment before and after VTA-DBS. The patients were evaluated on headache frequency, severity, and load (HAL) as well as on tests of generic quality of life (Short Form-36 (SF-36)), mood (Beck Depression Inventory, Hospital Anxiety and Depression Rating Scale), and pain (McGill Pain Questionnaire, Headache Impact Test, Pain Behaviour Checklist).ResultsThe CH-QoL total score was significantly reduced after compared to before VTA-DBS. Changes in the CH-QoL total score correlated significantly and negatively with changes in HAL, the SF-36, and positively and significantly with depression and the evaluative domain on the McGill Pain Questionnaire.ConclusionsOur findings demonstrate that changes after VTA-DBS in CH-QoL total scores are associated with the reduction of frequency, duration, and severity of headache attacks after surgery. Moreover, post VTA-DBS improvement in CH-QoL scores is associated with an amelioration in quality of life assessed with generic measures, a reduction of depressive symptoms, and evaluative pain experience after VTA-DBS. These results support the sensitivity to change of the CH-QoL and further demonstrate the validity and applicability of CH-QoL as a disease specific measure of quality of life for CH.     

Headache and Stress in a Group of Nurses and Government Administrators in Japan

We surveyed a group of 311 nurses and 283 mid-level government administrators in Yamagata Prefecture, Japan, to determine the prevalence and character of their headaches. We investigated the relationship of headaches to the subjects' stress, and their behaviour and coping patterns. The questionnaire we administered explored background factors, as well as the state of the respondents' mental health, life events, work motivation, support system, and interpersonal relationships.
The questionnaire was completed by 76.8% of nurses and 100% of administrators. Of these, 40.6% of nurses and 19.1% of the administrators reported recurrent headaches Furthermore, the number of headache sufferers among the women administrators was significantly higher than in the men. The nurses and the administrators who reported headache scored significantly higher than the nonheadache groups on the questions measuring symptoms of burnout, General Health Questionnaire, and learned helplessness. The group of nurses with headache had higher scores for life events, decreased work motivation. and nervous behavior than the nonheadache group; the administrators with headache scored higher for daily hassles than those of the nonheadache groups. In this study of a Japanese sample, the character of the subjects' headache and the possible inducing factors are consistent with those reported in studies of Europeans and Americans using similar testing methods. However, the high prevalence of headache among nurses and women administrators seems to be related to psychological stress, particularly work stress, which may be characteristic in Japan.     

Psychosocial aspects of chronic daily headache

The objective was to investigate possible psychosocial factors in chronic daily headache (HA) by comparing those with chronic daily HA to matched patients with chronic episodic HA and to matched non–HA controls. Although there is some research on psychosocial factors in chronic daily HA, it is conflicting and none to date has compared such patients to both an episodic HA control and a non–HA control. Nineteen patients with chronic daily HA (less than 2% of 4–times–per–day HA ratings were zero) were compared to 19 HA patients matched on age, gender and nominal IHS diagnoses, and to 16 similarly matched non–HA controls on measures of psychological distress (MMPI, BDI, STAI), measures of life stress (major past events, hassles, prospective daily stress) and quality of life (SF–36). Those with chronic daily HA were significantly more distressed and had significantly poorer function on most measures relative to non–HA controls. Although there were many arithmetic trends for chronic daily HA to be more distressed and to function less well than those with episodic HA, only on the depression and social introversion scales of the MMPI and the overall vitality rating of the SF–36 were the differences significant. All three groups had comparable levels of life stress regardless of how it was measured. Those with chronic daily HA have greater levels of psychological distress and poorer quality of life than those with episodic HA or non–HA controls, despite comparable levels of life stress.     

Interaction of cognitive appraisals of stressful events and coping: Testing the goodness of fit hypothesis

The present study investigated interactions between cognitive appraisals of, and coping with, stressful life events and their relationship with psychological symptomatology. Specifically, the goodness of fit between appraisals of the controllability of events and the use of problem- and emotion-focused coping was assessed for major life events and daily hassles. In relation to major life events, symptomatology was high when there was a poor fit between appraisals and coping (e.g., trying to change a stressor that was appraised as uncontrollable) and low when there was a good fit between appraisals and coping (e.g., palliating one's emotions when a stressor was perceived as uncontrollable). No effects were found in relation to daily hassles. Results were generally consistent with cognitive-transactional models of stress and coping.The authors wish to thank Sue Rolka for her assistance in data collection and analysis, Harold Leitenberg for comments on an earlier draft of this paper, and Carol Miller and David Howell for comments regarding data analysis.     

Whites and African-Americans in headache specialty clinics respond equally well to treatment

This study sought to determine if Whites and African-Americans respond similarly to headache treatment administered in 'real-world' headache specialty treatment clinics. Using a naturalistic, longitudinal design, 284 patients receiving treatment for headache disorders completed 30-day daily diaries that assessed headache frequency and severity at pretreatment and 6-month follow-up and also provided data on their headache disability and quality of life at pretreatment and 1-, 2- and 6-month follow-up. Controlling for socioeconomic status and psychiatric comorbidity, hierarchical linear models found that African-Americans and Whites reported significant reductions in headache frequency and disability and improvements in life quality over the 6-month treatment period. African-Americans, unlike Whites, also reported significant decreases in headache severity. Nevertheless, Africans-Americans had significantly more frequent and disabling headaches and lower quality of life after treatment relative to Whites. Although Whites and African Americans responded favourably to headache treatments, more efficacious treatments are needed given the elevated level of headache frequency that remained in both racial groups following treatment.     

Headache and other types of chronic pain

OBJECTIVE: To compare pain severity, disability, psychological distress, and quality of life between patients with headache and nonheadache treatment-seeking chronic pain patients. METHODS: Six hundred forty-three patients seeking treatment at a university pain clinic were divided into 3 categories based on primary pain complaint and the presence of focal or diffuse pain complaints: headache, nonheadache focal (pain involving <50% of the body), and nonheadache diffuse (pain involving >/=50% of the body). Patients completed questionnaires to identify pain severity, disability, depression, anxiety, and quality of life. RESULTS: Patients with headache differed from nonheadache patients for all evaluated parameters. Average pain severity on a 0 to 10 point severity scale was 5.55 for headache, 6.93 for nonheadache focal, and 8.05 for nonheadache diffuse. Pain occurred an additional 1.51 to 1.71 days per week for patients without headache. Compared to patients with headache, patients without headache reported greater frequency of reduced daily activities and complete disability related to pain. In addition, patients without headache and with diffuse pain reported more depression (78.2% vs. 45.8%) and anxiety (70.0% vs. 39.1%) than patients with headache. Quality of life measures were significantly reduced in patients with either nonheadache focal or diffuse conditions compared to patients with headache. CONCLUSIONS: Even when considering patients with focal rather than diffuse chronic pain complaints, patients with headache are dissimilar from other patients with chronic pain. Pain severity, frequency, disability, psychological distress, and quality of life are significantly more prominent or impaired in patients with chronic pain without headache compared to patients with headache.     

Chronic frequent headache in the general population: comorbidity and quality of life

We studied the nature and extent of comorbidity of chronic frequent headache (CFH) in the general population and the influence of CFH and comorbidity on quality of life. Subjects with CFH (headache on >14 days/month) were identified in a general health survey. We sent a second questionnaire including questions on comorbidity and quality of life to subjects with CFH and subjects with infrequent headache (IH) (1-4 days/month). We recoded comorbidity by using the Cumulative Illness Rating Scale (CIRS) and measured quality of life with the RAND-36, a Dutch version of Short Form-36. CFH subjects (n = 176) had higher comorbidity scores than the IH subjects (n = 141). Mean CIRS scores were 2.94 for CFH and 1.55 for IH [mean difference 1.40, 95% confidence interval (CI) 0.91, 1.89]. The mean number of categories selected was 1.92 in CFH and 1.10 in IH (mean difference 0.82, 95% CI 0.54, 1.11). Fifty percent of CFH subjects had a comorbidity severity level of at least 2, indicating disorders requiring daily medication, compared with 28% of IH subjects (mean difference 22%, 95% CI 12, 33). CFH subjects had more musculoskeletal, gastrointestinal, psychiatric and endocrine/breast pathology than IH subjects. Quality of life in CFH subjects was lower than that of IH subjects in all domains of the RAND-36. Both headache frequency and CIRS score had a negative influence on all domains. We conclude that patients with CFH have more comorbid disorders than patients with infrequent headaches. Many CFH patients have a comorbid chronic condition requiring daily medication. Both high headache frequency and comorbidity contribute to the low quality of life in these patients.     

Migraine frequency and intensity: relationship with disability and psychological factors

BACKGROUND: Migraine can be disabling, but it varies greatly in frequency and intensity between individuals. It is not clear which clinical features have the greatest impact on a migraineur's quality of life. OBJECTIVE: To determine the influence of headache intensity and frequency on headache-related disability. METHODS: Patients who were referred to a headache clinic and given a diagnosis of migraine with or without aura or transformed migraine (n = 115) were divided into different groups based on headache frequency and mean headache intensity. Headache frequency was determined from patient diaries. Headache intensity also was assessed from patient diaries and from scores on the pain severity scale of the Multidimensional Pain Inventory (MPI). Headache-related disability was assessed with the Headache Disability Inventory and by scores on the activity interference scale of the MPI. The degree of depression present was assessed with the Beck Depression Inventory, and emotional distress was measured by scores on the affective distress scale of the MPI. RESULTS: In our patient population, higher mean headache intensity levels were associated with higher levels of headache-related disability. Our results also suggested that increased headache intensity is associated with higher levels of depression and emotional distress, although this correlation was statistically significant in only 1 of 4 comparisons. Headache frequency did not correlate with disability, depression, or emotional distress. CONCLUSIONS: For a headache referral population, headache intensity appears to be a major determinant of headache-related disability, and it also correlates, to some extent, with the degree of depression and emotional distress present. Headache frequency was not clearly related to disability or psychological factors.     

Safety and efficacy of deep brain stimulation in refractory cluster headache: a randomized placebo-controlled double-blind trial followed by a 1-year open extension

Chronic cluster headache (CCH) is a disabling primary headache, considering the severity and frequency of pain attacks. Deep brain stimulation (DBS) has been used to treat severe refractory CCH, but assessment of its efficacy has been limited to open studies. We performed a prospective crossover, double-blind, multicenter study assessing the efficacy and safety of unilateral hypothalamic DBS in 11 patients with severe refractory CCH. The randomized phase compared active and sham stimulation during 1-month periods, and was followed by a 1-year open phase. The severity of CCH was assessed by the weekly attacks frequency (primary outcome), pain intensity, sumatriptan injections, emotional impact (HAD) and quality of life (SF12). Tolerance was assessed by active surveillance of behavior, homeostatic and hormonal functions. During the randomized phase, no significant change in primary and secondary outcome measures was observed between active and sham stimulation. At the end of the open phase, 6/11 responded to the chronic stimulation (weekly frequency of attacks decrease >50%), including three pain-free patients. There were three serious adverse events, including subcutaneous infection, transient loss of consciousness and micturition syncopes. No significant change in hormonal functions or electrolytic balance was observed. Randomized phase findings of this study did not support the efficacy of DBS in refractory CCH, but open phase findings suggested long-term efficacy in more than 50% patients, confirming previous data, without high morbidity. Discrepancy between these findings justifies additional controlled studies (clinicaltrials.gov number NCT00662935).     

Headache prevalence in the population of L��Aquila (Italy) after the 2009 earthquake

Stress induced by the events of daily life is considered a major factor in pathogenesis of primary tension-type headache. Little is known about the impact that could have a more stressful event, like a natural disaster, both in patients with chronic headache, both in people that do not had headache previously. The aim of the present study was to observe the prevalence of headache in the population following the devastating earthquake that affected the province of L'Aquila on April 6, 2009. The study population was conducted in four tent cities (Onna, Bazzano, Tempera-St. Biagio, Paganica). Sanitary access is recorded in the registers of medical triage, in the first 5 weeks, after the April 6, 2009. The prevalence of primary headache presentation was 5.53% (95% CI 4.2-7.1), secondary headache was 2.82% (95% CI 1.9-4.9). Pain intensity, assessed by Numerical Rating Scale score showed a mean value of 7±1.1 (range 4-10). The drugs most used were the NSAIDs (46%) and paracetamol (36%), for impossibility of finding causal drugs. This study shows how more stressful events not only have an important role in determining acute exacerbation of chronic headache, but probably also play a pathogenic role in the emergence of primary headache. Also underlines the lack of diagnostic guidelines or operating protocols to early identify and treat headache in the emergency settings.     

How Well Do Headache Patients Remember? A Comparison of Self-Report Measures of Headache Frequency and Severity in Patients with Migraine

Objective.— To compare patient recall of migraine headache frequency and severity over 4 weeks prior to a return visit as reported in an interval questionnaire vs a daily diary.
Background.— Many therapeutic decisions in the management of migraine patients are based on patient recall of response to treatment. As consistent completion of a daily headache diary is problematic, we have assessed the reliability of patient recall in a 1-time questionnaire.
Methods.— Headache frequency and average severity (0 to 3-point scale) were reported in an interval questionnaire by 209 patients who had also maintained a daily diary over the same 4-week period.
Results.— Headache frequency over the previous 4 weeks as reported in interval questionnaires (14.7) was not different from that documented in diaries (15.1), P  = .056. However, reported average headache severity on a 0 to 3 scale as reported in the questionnaire (1.84) was worse than that documented in the diaries (1.63), P  < .001.
Conclusions.— In the management of individual patients, the daily diary is still preferable when available. Aggregate assessment of headache frequency in groups of patients based on recall of the prior 4 weeks is equally as reliable as a diary. Headache severity reported in questionnaires tends to be greater than that documented in daily diaries and may be less reliable.     

An open-label dose-titration study of the efficacy and tolerability of tizanidine hydrochloride tablets in the prophylaxis of chronic daily headache

OBJECTIVE: To assess effectiveness and safety of tizanidine hydrochloride tablets for the prophylaxis of chronic daily headache. BACKGROUND: Tizanidine hydrochloride is an alpha2-adrenergic agonist that inhibits the release and effectiveness of norepinephrine at both central sites (eg, the locus ceruleus) and the spinal cord. It acts as a central muscle relaxant and has antinociceptive effects. Preliminary research and retrospective analyses have suggested efficacy in treatment of both chronic tension-type headache and chronic daily headache with migrainous features. DESIGN: Thirty-nine patients with more than 15 headache days per month (33 with migraine, 5 migrainous, 1 chronic tension-type) completed a 4-week baseline, with 31 completing a planned 12 weeks of treatment with tizanidine. Dosing was titrated from 2 mg at bedtime to a median daily dose of 14 mg (mean, 13.5; SD, 4.3; range, 4 to 20, divided over three doses per day) by treatment week 4. RESULTS: The overall headache index through week 12 (headache frequency x average intensity x duration) declined significantly (P<.00000002), with a corresponding increase in mean percentage improvement from 49% for weeks 1 through 4, to 65% for weeks 5 through 8, and 64% for weeks 9 through 12 (P<.0182). During weeks 9 through 12, 67% had improved more than 50% compared to baseline. Overall headache frequency declined from 22.83 to 15.83 days per month (P<.00001), with frequency of severe headaches dropping from 7.52 to 3.58 days per month (P<.000035). Average headache intensity dropped from 1.83 to 1.07 (1-to-5 scale), peak intensity declined from 2.37 to 1.40, and mean duration was reduced from 6.96 to 4.00 hours per headache (P<.00001). Improvement also occurred on visual analog scales of overall headache status, mood, sleep, quality of life (P<.00001), and sexual function (P<.0075); as well as the Beck Depression Inventory-II (P<.00073). Mild-to-moderate adverse events reported by more than 10% of the patients included somnolence, asthenia, and dry mouth. Only 3 patients discontinued treatment due to adverse events: somnolence and dry mouth alone (n = 1), or in combination with either hyperkinesis (n = 1) or constipation (n = 1). One patient had elevated liver enzymes that returned to normal after the drug was discontinued. CONCLUSIONS: The results provide preliminary support for the efficacy, safety, and tolerability of tizanidine in the prophylaxis of chronic daily headache.     

Gender and mood as mediators of the relationship between attributional style,daily life events,depression symptoms,and hopelessness

A study was conducted to investigate whether or not the relationship between attributional style, daily life events or hassles, and hopelessness depression is mediated by gender and mood at the time when attributional style is assessed. Measures of attributional style, hassles, depression, and hopelessness were administered, in a prospective design, to 100 undergraduate students on two occasions separated by 1 month. Results showed that the interaction of attributional style, hassles, and gender predicted change in hopelessness levels (p <.05) and that this interaction demonstrated a nonsignificant trend toward predicting change in depression symptom levels (p =.07). The interaction of attributional style, hassles, and time 1 depression scores also demonstrated a nonsignificant trend toward predicting change in depression symptom levels (p =.08), but did not predict change in hopelessness levels. The interaction of attributional style and hassles did not, by itself, predict change in either depression or hopelessness levels. These findings suggest that research investigating relationships between causal attributions for negative life events and depression should consider the potential influences of gender and of mood at the time when causal attributions are assessed.
