The Role of Peer Rejection in the Link between Reactive Aggression and Academic Performance

Background

There is substantial evidence to suggest that aggressive behavior is associated with poor academic performance in school-aged children. However, less is known about how different subtypes of aggression are related to academic performance and what variables may account for this association.

Objective

The current study examined unique associations between reactive (aggression in response to provocation) and proactive (goal-oriented calculated aggression) subtypes of aggression and academic performance. Further, the study evaluated whether peer rejection accounted for the link between these aggression subtypes and academic problems.

Methods

Study questions were examined using a sample of 147 school-age children (M = 8.22, SD = 1.99, 54.4 % male) who attended a community-based after school program. Path models were used to estimate the proposed associations using Mplus 6.12 statistical software.

Results

As expected, findings indicated that high levels of reactive, not proactive, aggression were uniquely associated with low levels of academic performance, and peer rejection accounted for this association.

Conclusions

Results advance the literature linking aggression and academic difficulties by indicating that reactive aggression, but not proactive aggression, is associated with academic difficulties. Findings also support previous literature suggesting that peer relationships are an important target of prevention and intervention efforts aimed at improving school performance, particularly for individuals who exhibit reactively aggressive behavior.     

Functions of Aggression and Disciplinary Actions Among Elementary School-Age Youth

Background

A link between aggression and disciplinary actions has been established; however, specific associations between reactive and proactive functions of aggression and disciplinary actions in the elementary school setting have not been evaluated. A better understanding of links between functions of aggression and disciplinary actions could directly inform whom to target and how to intervene to reduce infractions at school before more serious consequences (i.e., suspension or expulsion) occur.

Objective

The present study evaluated unique associations between reactive and proactive aggression and increases in disciplinary actions at school over the course of 1 year.

Methods

A sample of 173 elementary school-age youth (ages 8–10, 55.5% female) participated in the current study, with teacher and student reports as well as school record data collected.

Results

Correlation analyses indicated that both reactive and proactive aggression were associated with increases in disciplinary actions; however, the magnitude of effects was stronger for reactive aggression. Further, path analyses indicated that when simultaneously evaluating reactive and proactive aggression, only reactive aggression was uniquely positively associated with increases in disciplinary actions.

Conclusions

Reactive aggression appears to be the function of aggression to target for the prevention of disciplinary actions in the elementary school setting. Findings and their implications for intervention and future research are discussed.

     

Correlates of objectively measured physical activity in adults and older people: a cross-sectional study of population-based sample of adults and older people living in Norway

Objectives

The aims of the study were to identify correlates of objectively measured physical activity and to determine whether the explanatory power of the correlates differed with sex, weight status or level of education.

Methods

Physical activity was assessed objectively in 3,867 participants, aged 20–85 years, for a consecutive 7 days using the ActiGraph GT1M activity monitor. Demographic and biological variables and levels of psychological, social environmental and physical environmental correlates were self-reported.

Results

The complete set of correlates explained 18.6 % (p < 0.001) of the variance in overall physical activity. Age and physical activity identity were the most important factors, explaining 4.8 and 3.2 % of the variance, respectively, whereas social environmental and physical environmental correlates did not significantly increase the amount of explained variance. Small interaction effects between demographic and biological variables and the correlates were observed.

Conclusions

Self-efficacy, perceived behavioural control and physical activity identity might be important targets for intervention. Intervention efforts aimed at influencing psychological correlates of physical activity may prove equally effective regardless of sex, weight status and level of education.     

No negative effects of a multi-factorial, intensified treatment on self-reported health status, treatment satisfaction, and diabetes-related distress in screen-detected type 2 diabetes patients. The ADDITION-Netherlands study

Purpose

To examine the effects of a multi-factorial, intensified treatment on self-reported health status, treatment satisfaction, and diabetes-related distress in screen-detected type 2 diabetes patients.

Methods

Cluster-randomised controlled trial; A total of 498 screen-detected type 2 diabetes patients from 79 general practices were assigned to intensified (n = 255) or routine treatment according to Dutch guidelines (n = 243). At baseline and after 3 years, patients completed the Short Form-36 and the European Quality of Life-5 Dimensions questionnaires. After 4.5 years, patients completed the Diabetes Treatment Satisfaction Questionnaire and the Problem Areas In Diabetes scale. We analysed the effects of intensified treatment on self-rated health status, treatment satisfaction, and diabetes-related distress, using random effects models to account for clustering at practice level.

Results

Three to 5 years after type 2 diabetes was detected by screening, there were no differences between intensified and routine treatment in self-reported health status, treatment satisfaction, and diabetes-related distress.

Conclusions

Multi-factorial, intensified treatment did not influence self-rated health status, treatment satisfaction, and distress in screen-detected type 2 diabetes patients. Therefore, health care professionals do not have to fear negative effects of an intensified treatment on these psychological outcomes.     

Self-reported rate of eating is associated with higher circulating ALT activity in middle-aged apparently healthy Japanese men

Purpose

Elevated circulating activities of alanine aminotransferase (ALT), a marker for liver injury, and the lifestyle of a higher rate of eating in healthy and preclinical subjects are associated with increased risk of obesity and diabetes. In this study, we examined the associations between self-reported rate of eating and circulating ALT activity in middle-aged apparently healthy Japanese men.

Methods

We conducted a cross-sectional study of 3,929 apparently healthy men aged 40–59 years (mean ± SD age, 49.2 ± 5.8 years; BMI, 23.5 ± 2.8 kg/m²) who participated in health checkups in Japan. We analyzed their clinical serum parameters and lifestyle factors, including self-reported rate of eating. Associations between self-reported rate of eating and liver injury markers [ALT, γ-glutamyl transpeptidase (GTP), and aspartate aminotransferase (AST)], other clinical parameters or lifestyle factors were determined using analysis of variance followed by Tukey’s test. Multivariate logistic regression analyses (MLRA) were performed with ALT activity as the dependent variable and independent variables that included self-reported rate of eating.

Results

MLRA showed that ALT activity showed trends for higher self-reported rate of eating after adjustment for age, energy intake, and smoking status. The association between ALT activity and self-reported rate of eating disappeared after adjustment for BMI.

Conclusion

The results of this study show that ALT activity is positively associated with self-reported rate of eating in middle-aged apparently healthy Japanese men.     

Validity of self-reported BMI in older adults and an adjustment model

Study objectives

To determine reporting bias of self-reported vs. measured anthropometrics (body weight, height, body mass index, BMI), and to adjust self-reported BMI regarding the bias.

Methods

We compared self-reported with measured anthropometrics utilizing 659 control persons (age mean 68; range 37 to 80 years) from a case-control stroke study. The Bland-Altman approach examined the agreement between self-reported and measured values. A linear model was applied to correct the bias dependent on sex, age and self-reported BMI.

Results

Under-reporting of weight and over-reporting of height was found. On average, this resulted in lower self-reported BMIs by 1.0 kg/m² in men, 1.2 kg/m² in women (p?<?0.001). Bias correction of self-reported BMIs was derived from self-reported BMI (p?<?0.001), age (p?<?0.001), age-BMI interaction (p?<?0.001) and sex (p?<?0.05). Under-estimation of correct BMI resulted in the under-estimation of an overweight prevalence, with relatively low sensitivity regarding self-reported values (88 %). Our estimates should be recalibrated, if applied to other studies.

Conclusion

Self-reported anthropometric measures are systematically biased despite high correlations with measured values. A correction removes the average bias and improves accuracy.     

Nativity and cognitive disability among children: a unique comparison with reduced selection bias

Objectives

We examined the impact of nativity on self-reported cognitive disability by comparing children who were born outside of the USA (first-generation immigrants) with US-born offspring (second-generation immigrants) of foreign-born parents.

Methods

We analyzed a diverse, nationally representative, sample of 77,324 first-generation immigrant and second-generation immigrant children (aged 5–17 years) from the 2009 American Community Survey. Multivariate logistic regression was used to assess the association between nativity and self-reported cognitive disability after adjustment for demographics and household characteristics.

Results

Self-reported cognitive disability was observed in 1.7 % of the sample. The prevalence was higher among first second-generation immigrants than among second first-generation immigrants (1.9 vs 1.1 %, p < 0.001). After multivariate adjustment, the advantage of being foreign-born remained (OR = 0.63, 95 % CI = 0.53–0.75). Further analysis revealed effect modification of the immigrant health advantage by household income (p = 0.003).

Conclusions

We observed an immigrant advantage in self-reported cognitive disability; however, it was only evident among economically disadvantaged children. Future research should examine the contribution of the accumulation of poverty over time to the relationship between nativity and children’s health.     

Does work-site physical activity improve self-reported psychosocial workplace factors and job satisfaction? A randomized controlled intervention study

Purpose

To investigate whether a work-site strength-training program has a positive effect on self-reported psychosocial workplace factors and job satisfaction.

Methods

We conducted a randomized controlled trial among laboratory technicians implementing neck and shoulder exercises for pain relief, with 199 participants in the training group and 228 in the control group. Influence at work, sense of community, time pressure, and job satisfaction were measured with the Copenhagen Psychosocial Questionnaire at baseline and post-intervention after 20 weeks.

Results

There was no statistically significant change in any of the four variables in the training group from baseline to follow-up (all p ≥ 0.39). When we used MANOVA to test for between-group effects over time, we did not find any statistically significant result (all p > 0.14).

Conclusions

This study does not provide evidence for an effect of a work-site strength-training program on self-reported psychosocial workplace factors and job satisfaction.     

Validation of a new patient-generated questionnaire for quality of life in an urban sample of elder residents

Purpose

To provide evidence for the validity of the Fragebogen zur Lebensqualität multimorbider älterer Menschen (FLQM; English: Quality of life in elders with multimorbidity), a new tool for the assessment of life-satisfaction as a subjective indicator of quality of life in old age.

Methods

The FLQM measures overall life-satisfaction based on those self-generated domains in life that are most important to the respondent. Construct validity (correlations with convergent and divergent scales) and differential validity (subgroup differences with respect to age and limitations in everyday functioning) were analyzed in an urban sample of older adults (n = 299; 54.6% male; Mean (age) = 75.65 years, SD = 6.57).

Results

Correlations of FLQM with measures of similar constructs were close (r = 0.35–0.50; p < 0.001). There were no age-group differences. However, subjects with self-reported impairment in functioning scored significantly lower on the FLQM. Also, the relationship between FLQM and self-rated health was close (r = 0.44; p < 0.001).

Conclusions

The FLQM is a valid assessment of older peoples’ life-satisfaction. The focus on domains of utmost individual importance seems to link the FLQM to self-rated health more closely than other ratings of global life-satisfaction. Further investigation into the qualitative information obtained by the FLQM is desirable in order to explain individual compositions of life-satisfaction and overall quality of life.     

Adolescents’ Self-reported Running Away from Home and Suicide Attempts During a Period of Economic Recession in Greece

Background

Running away from home and suicide attempts during adolescence are high-risk behaviors for safety and health, and a “way out” from negative life experiences.

Objective

To examine the self-reported prevalence of running away and suicide attempts among adolescents in Greece in the midst of a severe economic recession which is exerting pressure on families, and to identify associated psychosocial factors.

Methods

Data were drawn from a nationally representative school survey (n = 23,279, 15–19 years old). Students answered in their classrooms an anonymous questionnaire under the supervision of trained researchers.

Results

Each behavior was reported by one in nine adolescents (11.3 % for lifetime suicide attempts and 11.6 % for lifetime running away). Among those who reported the one behavior, a quarter also reported the other. Logistic regression analyses indicated that these behaviors share several common psychosocial correlates: family related (quality of parental relationships, parental monitoring), school related (poor performance and dissatisfaction), substance use, and emotional, psychological and behavioral problems. Gender was a significant correlate but in opposite directions for running away (more common among boys) and suicide attempts (more common among girls). Socioeconomic status was not a significant correlate for either behavior, possibly because the impact of the economic crisis on parents had not yet filtered down to their children in 2011 (the survey year).

Conclusions

Findings suggest the need for timely interventions towards vulnerable youth and their families by identifying personal, familial and school factors associated with these two health- and life-compromising behaviors.     

Mortality in nursing home residents without cognitive impairment and its relation to self-reported health-related quality of life, sociodemographic factors, illness variables and cancer diagnosis: a 5-year follow-up study

Purpose

It is generally known that health-related quality of life (HRQOL) predicts cause-specific mortality. Few studies have explored whether generic self-reported HRQOL, sociodemographic factors and illness variables are independently associated with mortality among cognitively intact nursing home (NH) residents with and without cancer. We hypothesized that sociodemographic factors and illness variables would be associated with mortality and that HRQOL, measured using the SF-36 Health Survey, would predict mortality among NH residents with and without cancer.

Methods

We followed a cohort of 227 cognitively intact (Clinical Dementia Rating scale score ≤0.5) older residents (60 with cancer and 167 without) from 30 NH from 2004–2005 to 2010. We collected data by face-to-face interview. We obtained sociodemographic variables and medical diagnoses from the records.

Results

Survival did not differ between residents with and without cancer (P = 0.31). Twenty percent of the residents with cancer and 13% without cancer were still alive. After adjustment for sociodemographic and illness variables, increasing age (P < 0.001), higher education (P = 0.009), comorbidity (P = 0.04) and the subdimension physical functioning (P = 0.009) predicted mortality. Bodily pain was only marginally associated with mortality (P = 0.08).

Conclusions

Independent of cancer, HRQOL and comorbidity predicted mortality among NH residents without cognitive impairment.     

Measurement properties of questionnaires assessing participation in children and adolescents with a disability: a systematic review

Purpose

To critically appraise the measurement properties of questionnaires measuring participation in children and adolescents (0–18 years) with a disability.

Methods

Bibliographic databases were searched for studies evaluating the measurement properties of self-report or parent-report questionnaires measuring participation in children and adolescents (0–18 years) with a disability. The methodological quality of the included studies and the results of the measurement properties were evaluated using a checklist developed on consensus-based standards.

Results

The search strategy identified 3,977 unique publications, of which 22 were selected; these articles evaluated the development and measurement properties of eight different questionnaires. The Child and Adolescent Scale of Participation was evaluated most extensively, generally showing moderate positive results on content validity, internal consistency, reliability and construct validity. The remaining questionnaires also demonstrated positive results. However, at least 50 % of the measurement properties per questionnaire were not (or only poorly) assessed.

Conclusions

Studies of high methodological quality, using modern statistical methods, are needed to accurately assess the measurement properties of currently available questionnaires. Moreover, consensus is required on the definition of the construct ‘participation’ to determine content validity and to enable meaningful interpretation of outcomes.     

Impaired parent-reported health-related quality of life of underweight and obese children at elementary school entry

Purpose

Examine the health-related quality of life of 5–6-year-old underweight, overweight and obese children.

Methods

Our cross-sectional study included 3,227 parent–child dyads from the “Be active, eat right” study. Parents completed questionnaires regarding child and parental characteristics. Health-related quality of life of the child was measured using the Child Health Questionnaire Parent Form 28. Children were classified normal weight, overweight, obese, severely obese, and underweight according to the international age and gender BMI cutoff points. Bootstrap analyses were performed for general linear models corrected for potential confounding variables.

Results

Severely obese children (β, ?2.60; 95 % CI, ?4.80 to ?0.57, p < 0.01) and underweight children (β, ?1.11; 95 % CI, ?1.85 to ?0.39, p < 0.01) had lower parent-reported scores on the physical summary scale. On the physical functioning profile scale parents of overweight and severely obese children also reported statistically significant lower scores (p < 0.05 and p < 0.01, respectively).There were no significant differences regarding the psychosocial summary scale scores between the different weight categories.

Conclusion

Underweight and overweight children experience impaired health-related quality of life on the physical functioning domain. Physicians, teachers and parents should be aware of the possible negative impact on health-related quality of life in underweight and overweight 5–6-year-old children.     

Determinants of quality of life in Spanish transsexuals attending a gender unit before genital sex reassignment surgery

Purpose

To evaluate the self-reported perceived quality of life (QoL) in transsexuals attending a Spanish gender identity unit before genital sex reassignment surgery, and to identify possible determinants that likely contribute to their QoL.

Methods

A sample of 119 male-to-female (MF) and 74 female-to-male (FM) transsexuals were included in the study. The WHOQOL-BREF scale was used to evaluate self-reported QoL. Possible determinants included age, sex, education, employment, partnership status, undergoing cross-sex hormonal therapy, receiving at least one non-genital sex reassignment surgery, and family support (assessed with the family APGAR questionnaire).

Results

Mean scores of all QoL domains ranged from 55.44 to 63.51. Linear regression analyses revealed that undergoing cross-sex hormonal treatment, having family support, and having an occupation were associated with a better QoL for all transsexuals. FM transsexuals have higher social domain QoL scores than MF transsexuals. The model accounts for 20.6 % of the variance in the physical, 32.5 % in the psychological, 21.9 % in the social, and 20.1 % in the environment domains, and 22.9 % in the global QoL factor.

Conclusions

Cross-sex hormonal treatment, family support, and working or studying are linked to a better self-reported QoL in transsexuals. Healthcare providers should consider these factors when planning interventions to promote the health-related QoL of transsexuals.     

Determinant factors of the difference between self-reported weight and measured weight among Japanese

Objectives

To assess the difference between self-reported and measured weight values in Japanese men and women and to determine the underlying determinants of the differences between self-reported and measured values.

Methods

The data were collected from 363 general Japanese individuals aged 16–88 years living in Kumamoto prefecture. Participants completed a self-administered questionnaire designed for this study with self-reported weight and height values. Measured weight and height were measured immediately after questionnaire completion. Paired t-tests identified differences between self-reported and measured values by sex. Multiple-stepwise regression analysis examined the independent variables’ effects on the differences between self-reported and measured weights.

Results

Significant differences were found between self-reported and measured values for both sexes (p < 0.001). There was a significant negative relationship between the difference in an individual’s self-reported and measured weight in each sex, with higher measured weight individuals more likely to underestimate their weight. Multiple-stepwise regression analysis models explained 12.1 % (p < 0.01), 11.3 % (p < 0.01), and 5.6 % (p < 0.01) of the variance in all participants, men, and women, respectively. Significant effects were found for age, weight measurement frequency, and measured weight in total participants, weight measurement frequency, and measured weight for men, and age for women.

Conclusions

In this study, the mean absolute value of the weight and height variances proved the unreliability of self-reported weight and height values. This study’s findings suggest self-reported weight inaccuracy especially for obese populations. This should be adjusted when using it in epidemiological studies and healthcare planning.

     

Health-related quality of life in the aftermath of child maltreatment: follow-up study of a hospital sample

Objective

In the aftermath of child maltreatment or neglect, the health-related quality of life (HRQoL) in children is likely to be affected. However, research on quality of life in maltreated children is lacking. The aim of this study is to compare the HRQoL in a follow-up sample of children referred to an interdisciplinary hospital child protection team (CPT) to match controls and to explore correlates of HRQoL.

Method

Of the 319 in- and outpatient children referred to the CPT at the University Children’s Hospital Zurich between 2005 and 2006, an eligible sample of 180 children was contacted for a follow-up. HRQoL was assessed for 42 former patients using the self- and proxy-rated KIDSCREEN-27 for children above the age of 6 years and the TAPQOL parent report for children younger than 6 years. HRQoL-scores in the maltreatment group were compared with HRQoL in 39 matched controls.

Results

Self-reported HRQoL in maltreated children above the age of 6 years was significantly impaired compared to matched controls. The caregiver-rated HRQoL of maltreated children, however, was not affected. Low socioeconomic status and number of life events were associated with impaired self-reported HRQoL. Analyzed together with these factors, maltreatment lost its predictive power on HRQoL.

Conclusion

Maltreated children and adolescents suffer from impaired HRQoL even after the maltreatment has been disclosed and targeted by interventions. The impact of socioeconomic environment reinforces the importance of a multidisciplinary and systemic approach to maltreatment as applied by the CPT. Although the nature of discordance between child and caregiver report is not known, researchers and clinicians are strongly encouraged to assess the victim’s self-reported HRQoL independently of their proxies’ view.     

Health-related quality of life in multiple sclerosis: role of cognitive appraisals of self,illness and treatment

Purpose

Health-related quality of life (HRQoL) is considered an important measure of treatment and rehabilitation outcomes in multiple sclerosis (MS) patients. In this study, we used multivariate regression analysis to examine the role of cognitive appraisals, adjusted for clinical, socioeconomic and demographic variables, as correlates of HRQoL in MS.

Methods

The cross-sectional study included 257 MS patients, who completed Multiple Sclerosis Impact Scale, Generalized Self-Efficacy Scale, Rosenberg Self-Esteem Scale, Brief Illness Perception Questionnaire, Treatment Beliefs Scale, Actually Received Support Scale (a part of Berlin Social Support Scale) and Socioeconomic Resources Scale. Demographic and clinical characteristics of the participants were collected with a self-report survey. Correlation and regression analyses were conducted to determine associations between the variables.

Results

Five variables, illness identity (β = 0.29, p ≤ 0.001), self-esteem (β = ?0.22, p ≤ 0.001), general self-efficacy (β = ?0.21, p ≤ 0.001), disability subgroup “EDSS” (β = 0.14, p = 0.006) and age (β = 0.12, p = 0.012), were significant correlates of HRQoL in MS. These variables explained 46 % of variance in the dependent variable. Moreover, we identified correlates of physical and psychological dimensions of HRQoL.

Conclusions

Cognitive appraisals, such as general self-efficacy, self-esteem and illness perception, are more salient correlates of HRQoL than social support, socioeconomic resources and clinical characteristics, such as type and duration of MS. Therefore, interventions aimed at cognitive appraisals may also improve HRQoL of MS patients.

     

Health-related quality of life in patients with interstitial cystitis/bladder pain syndrome and frequently associated comorbidities

Purpose

To estimate the association of chronic non-urologic conditions [i.e., fibromyalgia (FM), chronic fatigue syndrome (CFS), and irritable bowel syndrome (IBS)] with health-related quality of life (HRQOL) in patients with interstitial cystitis/bladder pain syndrome (IC/BPS).

Methods

A total of 276 women with established diagnoses of IC/BPS completed a telephone interview which included demographics, self-reported medical conditions, the SF-36 health survey, and the interstitial cystitis symptom index (ICSI). Multivariate linear regression analysis was used to identify correlates of SF-36 physical and mental component summary scores.

Results

Mean patient age was 45.1 (SD 15.9) years, and 83 % of the subjects were white. Mean values for the SF-36 Physical Component Score (PCS) and Mental Component Score (MCS) means were 39 (SD 14) and 45 (SD 12), respectively, indicating significant HRQOL reductions. Mean ICSI score was 11.27 (SD = 4.86). FM and IBS were significantly associated with worse SF-36 scores: ?8 points on the PCS (p < 0.001) and ?6 points on the MCS (p < 0.001). CFS and the presence of other pelvic conditions (overactive bladder, vulvodynia, endometriosis) were not significantly associated with SF-36 PCS and MCS scores.

Conclusions

In patients with IC/BPS, the presence of FM, CFS, and IBS has a significant association with HRQOL, equivalent in impact to the bladder symptoms themselves. These results emphasize the importance of a multidisciplinary approach to treating patients with IC/BPS and other conditions.     

Longitudinal construct validity of the Health Utilities Indices Mark 2 and Mark 3 in hip fracture

Purpose

The objective of this study is to evaluate the longitudinal construct validity of the Health Utilities Index Mark 2 (HUI2) and Health Utilities Index Mark 3 (HUI3) using a convergent/divergent validity approach in patients recovering from hip fracture, with the Functional Independence Measure (FIM) as the comparator.

Methods

A total of 278 patients with a primary diagnosis of hip fracture were interviewed 3–5 days after surgery and then at 1 and 6 months using the HUI2, HUI3 and the FIM and a Likert-type rating of hip pain. A priori hypotheses were formulated. Convergent and divergent correlations between HUI2, HUI3 and FIM change scores for the baseline to 1-month and baseline to 6-month intervals were examined.

Results

Overall HUI2 detected continued gain in health-related quality of life between 1 and 6 months after fracture, as the change increased from 0.20 to 0.29 units. The correlation between change in the overall HUI2 score and total FIM score was moderate (r = 0.50) over the 6-month interval, but larger than the observed correlation over the 1-month interval (r = 0.36). The correlation between change in overall HUI3 score and total FIM over the 1-month interval was small (r = 0.32), and the correlation between change in overall HUI3 score and total FIM was moderate (r = 0.37) over the 6-month interval. All hypotheses for the divergent correlations were supported.

Conclusions

Weaker correlations were reported for change over 1 month as compared to change over the 6 months after fracture. Findings supported the longitudinal construct validity of the overall HUI2 and HUI3 for the assessment of recovery following hip fracture, particularly for change over the 6 months following fracture.
