Is Measurement Noninvariance a Threat to Inferences Drawn from Randomized Control Trials? Evidence From Empirical and Simulation Studies

Randomized control trials (RCTs) are considered the gold standard when evaluating the impact of psychological interventions, educational programs, and other treatments on outcomes of interest. However, few studies consider whether forms of measurement bias like noninvariance might impact estimated treatment effects from RCTs. Such bias may be more likely to occur when survey scales are utilized in studies and evaluations in ways not supported by validation evidence, which occurs in practice. This study consists of simulation and empirical studies examining whether measurement noninvariance impacts treatment effects from RCTs. Simulation study results demonstrate that bias in treatment effect estimates is mild when the noninvariance occurs between subgroups (e.g., male and female participants), but can be quite substantial when being assigned to control or treatment induces the noninvariance. Results from the empirical study show that surveys used in two federally funded evaluations of educational programs were noninvariant across student age groups.     

INCREASING HANDICAPPED PRESCHOOLERS' PEER SOCIAL INTERACTIONS: CROSS-SETTING AND COMPONENT ANALYSIS

The purposes of our study were: (a) to train a set of observationally determined social behaviors via peer initiation; (b) to determine if effects generalized across classroom settings and to directly intervene if generalization did not occur; and (c) to analyze components of the peer-initiation intervention. After baseline, nonhandicapped preschool children (confederates) were taught to direct social initiations to the three handicapped preschool-aged students. Teachers prompted the confederates to engage the students in social interaction when necessary and rewarded the confederates with tokens. Confederates' initiations to the students resulted in increased frequencies of positive social interaction. There was no generalization to other classroom settings, and the intervention was subsequently implemented in a second and third classroom. Next, the confederates' token reinforcement system was withdrawn, with no apparent deleterious effects on the confederates' or students' social interactions. When teachers substantially reduced their prompts to the confederates, students' social interactions decreased. Finally, reinstatement of teacher prompts resulted in increases in the confederates' social initiations and, consequently, the positive social interactions of the students.     

Issues in group work with older lesbians

This article outlines considerations in group interventions with older lesbians. It is intended for mental health professionals who work—as leaders, supervisors, and consultants—with various kinds of groups in their professional practice, including therapy, psychoeducational, support, growth, recreational, and self-help groups. First, unique issues in the life circumstances of older lesbians are addressed. Next, five case examples are presented that illustrate the usefulness of group interventions with this population. The article concludes with recommendations for effective practice.     

In search of durable positive psychology interventions: Predictors and consequences of long-term positive behavior change

A number of positive psychology interventions have successfully helped people learn skills for improving mood and building personal resources (e.g., psychological resilience and social support). However, little is known about whether intervention activities remain effective in the long term, or whether new resources are maintained after the intervention ends. We address these issues in a 15-month follow-up survey of participants from a loving-kindness meditation intervention. Many participants continued to practice meditation, and they reported more positive emotions (PEs) than those who had stopped meditating or had never meditated. All participants maintained gains in resources made during the initial intervention, whether or not they continued meditating. Continuing meditators did not differ on resources at baseline, but they did show more PE and a more rapid PE response to the intervention. Overall, our results suggest that positive psychology interventions are not just efficacious but of significant value in participants’ real lives.     

Teaching happiness at school: Non-randomised controlled mixed-methods feasibility study on the effectiveness of Personal Well-Being Lessons

The paper presents an educational initiative to develop a separate well-being curriculum for a federation of schools in south-east London. A mixed-methods study was undertaken to evaluate the feasibility of the curriculum run biweekly in Year 7 (age 11–12, N = 96). The study utilised a non-randomised repeated measures design with a control group (N = 68) using general life satisfaction, domain life satisfaction and affect balance as outcome variables. In addition, semi-structured interviews were conducted with four students, two teachers and the principal of the intervention school. The results indicated significant buffering effect of the intervention in protecting students against the decline of satisfaction with self, satisfaction with friends, positive affect and the increase in negative affect throughout the first year of middle school. The qualitative data shed light on explicit learning, psychological outcomes and challenges associated with the programme. Overall, the data indicate a positive impact of the well-being curriculum.     

Counting blessings and sharing gratitude in a Chinese prisoner sample: Effects of gratitude-based interventions on subjective well-being and aggression

Abstract

Gratitude-based interventions are effective for increasing individuals’ subjective well-being (SWB); however, they have not been validated among prisoners, especially for negative states (i.e. aggression). Furthermore, as a social emotion, gratitude might be nurtured via practice within a social group. Therefore, we developed a weekly group-based sharing gratitude exercise, and examined its effect along with that of daily blessing-counting among prisoners in China. Ninety-six male violent prisoners were assigned randomly to three conditions (gratitude-sharing, blessing-counting, and control). Interventions took place over five weeks. Both interventions improved SWB and decreased aggression compared to controls. Additionally, the improvement in gratitude mediated the relationship between the two forms of intervention and SWB. These findings indicate that gratitude-based interventions can be implemented among male prisoners to help further the psychological corrective function of prisons in China.     

An ecological approach to child and family clinical and counseling psychology

The ecological model of child and family clinical and counseling psychology considers mental health service delivery within a health maintenance framework, approaching the complexity of children's behavior in a systematic and organized fashion using science-based intervention practices. The service delivery framework integrates assessment, intervention, and motivation at all phases of an intervention. Assessments enhance the participants' and professionals' appraisal, which in turn impact motivation to change. Interventions are sensitive to assessment-based targets and participant motivation. A menu of interventions range from assessment, feedback, and brief interventions to more extensive mental health services, potentially integrated with other community agencies and school settings. The ecological model suggests revisions in the conceptualization of child and adolescent psychopathology, training for mental health professionals, and strategies for the design and testing of interventions. In general, a reformulation of mental heath services for children and families within an ecological framework enhances the potential for integrating science and practice.     

The Effect of Active Supervision and Pre-correction on Minor Behavioral Incidents in a Sixth Grade General Education Classroom

This study examines the effect of using active supervision, pre-correction, and daily data review on occurrences of minor behavioral incidents in a sixth grade general education classroom. The results suggest a functional relationship between the use of the teacher-training package and concomitant decreases in minor behavioral incidents. The findings from this study extend the existing literature on the use of active supervision and pre-correction, and establish a useful model for bringing teachers in contact with proactive instructional strategies.
