Malleability of weight-biased attitudes and beliefs: A meta-analysis of weight bias reduction interventions

Weight bias exists across many important life domains, necessitating interventions designed to reduce weight-biased attitudes and beliefs. Though the effectiveness of weight bias interventions has been questioned, to our knowledge no meta-analysis of these interventions has been conducted. This meta-analysis evaluated the impact of weight bias interventions on weight-biased attitudes and beliefs and explored potential moderators. Interventions were eligible if they used an adult sample and a validated measure of weight-biased attitudes, which resulted in the inclusion of 30 studies represented in 29 articles. A random effects approach using inverse weights resulted in a mean effect size estimate of g = −0.33 (lower scores indicate less weight bias) for both attitudes and beliefs. Intervention type, publication type, and population type were not significant moderators but demonstrated noteworthy trends. Results reveal a small, positive effect of weight bias interventions on weight-biased attitudes and beliefs and provide useful information for future interventions.     

Mental Health and Adverse Childhood Experiences

The theoretical basis of occupational therapy interventions was investigated in two mental health facilities in the Midwestern United States. Using retrospective cohort and grounded theory designs, 121 medical records were reviewed and five occupational therapy practitioners were interviewed. Theoretical reasoning was not explicitly documented, but according to analysis, the behavioral/cognitive-behavioral model, client-centered models, and the model of human occupation were the most frequently used theories to guide interventions. Lack of documentation of theory use has significant implications for the value accorded to occupational therapy skills in health care. A larger study is recommended to increase external generalizability of the findings.     

Challenges and opportunities in moving toward a public health approach in school mental health

These three outstanding papers are important for the discipline of school psychology, the field of school-based mental health, and more generally for systems of education and mental health for children and adolescents. As the authors emphasize, there is an unprecedented focus on improving programs that remove barriers to learning and enhance development, health, and mental health in youth, in the most universal natural setting—the schools. The authors also correctly highlight that school psychology is uniquely positioned to play a leading role in this reform and change effort. Two interconnected themes of the public health approach—applying the evidence base and moving toward preventive and population-focused interventions—are emphasized in these papers, and while they focus on school psychology, the issues discussed are generalizable to the many disciplines that operate within educational and mental health systems. In the following discussion, I react to the papers' two major themes, discuss realities that should be addressed for progress to be made, and comment on their implications for school psychology.     

Young male drivers’ risky driving 15 months after licensure – The role of intervention,attitudes towards accompanied driving,and parents’ risk

An indispensable issue in contemporary research on risk-taking by young drivers is parents’ influence on their offspring’s driving behavior. The current study measures this influence by using a risk index of parents’ driving behavior measured via in-vehicle data recorders together with young drivers’ self-reported answers to a set of questionnaires. Both parents and young drivers participated in one of three intervention program groups to enhance safe driving within a longitudinal study, and the outcome of this intervention was measured 15 months following licensure. The aim of the current study was thus to assess the contribution of parents’ actual driving behavior, participation in the intervention, and teen drivers’ attitudes towards accompanied driving (measured six months after licensure), to the reported risky driving of the young drivers fifteen months after receiving their driving license. The data consist of a sample of 78 parent-young driver dyads who were originally randomly assigned to one of three intervention groups (receiving different forms of feedback) or a control group (with no feedback). Findings indicate that the feedback and training to parents intervention group, as well as parents’ risky driving events rate, were positively associated with the reported proneness to reckless driving and the reckless driving habits of the young drivers. In addition, lower perception of accompanied driving as enabling a sense of relatedness with parents, and higher negative perceptions of this period, were related to higher reported risky driving among young drivers fifteen months after licensure. The results highlight the importance of parents’ behavior and relationships with their offspring as key concepts in moderating risky driving among young drivers. Practical implications for road safety are discussed.     

The Experience in Personal Social Systems Questionnaire (EXIS.pers): Development and Psychometric Properties

This study presents the theoretical background, development, and psychometric properties of the German and English versions of the Experience in Personal Social Systems Questionnaire (EXIS.pers). It assesses how the members of a personal social system experience their situation within that system. It is designed as a research tool for interventions in which only one member of the system participates (e.g., Family Constellation Seminars). The EXIS.pers was created to measure change on the individual level relating to one's own important personal social system. In Study 1, we used exploratory factor analysis (EFA) for latent variable identification of the original German EXIS.pers (n = 179). In Studies 2 and 3, we used confirmatory factor analysis (CFA) to examine the dimensionality of the German (n = 634) and English (n = 310) EXIS.pers. Internal consistencies and cross‐cultural structural equivalence were assessed. EFA indicated that a four‐factor model provided best fit for the German EXIS.pers. For both the German and English EXIS.pers, CFA provided the best fit for a five‐factor bi‐level model that included a general factor (Experience In Personal Social Systems) and four dimensions (Belonging, Autonomy, Accord, Confidence). Good internal consistencies, external associations, and cross‐cultural structural equivalence were demonstrated. This study provides first evidence for the German and English EXIS.pers as an economical and reliable measure of an individual's experience within his or her personal social systems.     

Where science starts: spontaneous experiments in preschoolers' exploratory play

Probabilistic models of expected information gain require integrating prior knowledge about causal hypotheses with knowledge about possible actions that might generate data relevant to those hypotheses. Here we looked at whether preschoolers (mean: 54 months) recognize “action possibilities” (affordances) in the environment that allow them to isolate variables when there is information to be gained. By manipulating the physical properties of the stimuli, we were able to affect the degree to which candidate variables could be isolated; by manipulating the base rate of candidate causes, we were able to affect the potential for information gain. Children’s exploratory play was sensitive to both manipulations: given unambiguous evidence children played indiscriminately and rarely tried to isolate candidate causes; given ambiguous evidence, children both selected (Experiment 1) and designed (Experiment 2) informative interventions.     

Effectiveness of Cognitive/Behavioral Small Group Intervention for Reduction of Depression and Stress in Non-Hispanic White and Hispanic/Latino Women Dementia Family Caregivers: Outcomes and Mediators of Change

This study enrolled 184 middle-aged and older women (95 Non-Hispanic White and 89 Hispanic/Latino) who provided in-home hands-on care to an elderly relative with Alzheimer’s disease or another form of dementia. Within ethnic group they were randomly assigned to either a CBT-based small group intervention program called “Coping with Caregiving” (CWC) that taught a variety of cognitive and behavioral skills to reduce stress and depression, or to a minimal telephone based control condition (TSC). Intervention lasted about 4 months; one post-treatment assessment was completed 6 months after baseline by interviewers blind to the intervention condition. Interviews and interventions were conducted in English or Spanish by trained staff. Results indicated that those in the CWC (regardless of ethnicity) showed greater improvement from pre to post intervention than those in the TSC on measures of depressive symptoms, overall life stress, and caregiving-specific stress. In order to investigate if these changes may have been related to one proposed mechanism of change in CBT (skill utilization), a new measure was constructed. Change in frequency of use and perceived helpfulness of adaptive coping skills were assessed in all caregivers. Results indicated that caregivers in CWC reported greater frequency of use, and greater perceived helpfulness, of these skills at post intervention compared to caregivers in the TSC. Improvement measured by dependent measures was correlated with an increase in these indices for those in the CWC. Tests for mediation suggest that effective skill utilization may mediate the effect of treatment on outcome. Implications of these findings are discussed and recommendations provided for future research.     

Motivational climate interventions in physical education: A meta-analysis

Objective

The purpose of this study was to synthesize findings from motivational climate interventions employing [Ames, 1992a] and [Ames, 1992b] and [Epstein, 1988] and [Epstein, 1989] TARGET framework within school-based physical education contexts.

Design

The present study employed a quantitative research synthesis design. Meta-analysis uses empirical studies to summarize past research by drawing overall conclusions from separate investigations. This research design highlights important and unsolved issues related to motivational climate interventions within physical education.

Methods

Standard meta-analytic procedures incorporating inclusion and exclusion criteria, literature search, coding procedures, and statistical methods were used to identify and synthesize 22 studies with 24 independent samples. Cohen’s (1988) criteria for effect sizes were used to interpret and evaluate results.

Results

There was an overall small positive treatment effect (g = 0.103) for groups exposed to mastery motivational climates. Outcome analyses identified the most consistent and largest overall treatment effects for behavioral outcomes (g = 0.39–0.49) followed by affective outcomes (g = −0.27 to 0.59) and cognitive outcomes (g = −0.25 to 0.32). Moderator analyses were directed by study heterogeneity and identified several trends in intervention features and study features with the most substantial trend for participant features as elementary students had the largest overall treatment effect (g = 0.41).

Conclusions

Outcome and moderator analyses identified several trends in methodological features, participant features, and study features that should be addressed in future physical education motivational climate interventions.     

Latinx Mental Health Scholars' Experiences with Cultural Adaptation and Implementation of Systemic Family Interventions

An increasing number of culturally adapted family-level interventions address mental health disparities with marginalized populations in the United States. However, with these developments many barriers have arisen, such as challenges with degree of cultural fit, engagement, and sustainability. We conducted 12 elite phenomenological interviews with mental health scholars involved in prevention and intervention family research with various Latinx communities within and outside of the United States. These scholars discussed their experiences of overcoming barriers in their research. We used thematic analysis to code and analyze participant responses, and our findings support the gaps in previous literature and highlight potential pathways to overcoming barriers in cultural adaptation research. Themes included the need for: (a) better understanding of the intersection between culture and context; (b) community-centered approaches to addressing implementation challenges; and (c) structural changes within institutional, governmental, and political levels. We discuss implications for researchers and practitioners working with Latinx families.
