Some developments in multivariate generalizability

This article is concerned with estimation of components of maximum generalizability in multifacet experimental designs involving multiple dependent measures. Within a Type II multivariate analysis of variance framework, components of maximum generalizability are defined as those composites of the dependent measures that maximize universe score variance for persons relative to observed score variance. The coefficient of maximum generalizability, expressed as a function of variance component matrices, is shown to equal the squared canonical correlation between true and observed scores. Emphasis is placed on estimation of variance component matrices, on the distinction between generalizability- and decision-studies, and on extension to multifacet designs involving crossed and nested facets. An example of a two-facet partially nested design is provided.Appreciation is expressed to the Office of Research in Medical Education, University of Texas Medical Branch, for permitting use of their data.     

A simple test for heterogeneity of variance in complex factorial designs

A simple procedure for testing heterogeneity of variance is developed which generalizes readily to complex, multi-factor experimental designs. Monte Carlo Studies indicate that the Z-variance test statistic presented here yields results equivalent to other familiar tests for heterogeneity of variance in simple one-way designs where comparisons are feasible. The primary advantage of the Z-variance test is in the analysis of factorial effects on sample variances in more complex designs. An example involving a three-way factorial design is presented.     

Sex,sex role,and psychomotor reminiscence

Effects of sex and sex role on psychomotor reminiscence and task proficiency were investigated in samples of masculine males, masculine females, feminine males, and feminine females, as defined by the Bem Sex Role Inventory. Sex contributed significantly to the variance of reminiscence and to the slopes of prerest practice gains, as others have found. Sex role contributed virtually nothing to the variance of reminiscence, but feminine subjects of both sexes reached generally higher levels of performance than masculine subjects. Sex and sex role effects were orthogonal at all points of comparison.     

Clergy wives of the new generation

This article describes the changes that are occurring in the lives of wives of ministers, the difficulties and satisfactions they are experiencing, the issues they are confronting. It presents the thesis that the crucial change in the past 15 years for wives of ministers is that they no longer derive their primary identity from being ministers' wives, and therefore they are less involved in their husbands' ministries and more focused on their own issues and careers.Dr. Niswander is a pastoral counselor and senior staff member of the Pastoral Psychotherapy Institute, 1580 N. Northwest Highway, Park Ridge, Illinois 60068. She has been the wife of a United Methodist minister for 27 years and was recently ordained by that denomination as an elder herself. She has led retreats, workshops and study groups for wives of ministers as well as counseling them professionally.     

Spiritual Wellness for Clients With HIV/AIDS: Review of Counseling Issues

The epidemic of HIV/AIDS has resulted in an increasing population of individuals in need of counseling services: persons living with AIDS, as well as family, friends, and caregivers. The relationship between HIV/AIDS clients' counseling and spiritual issues is demonstrated by a review of salient literature. Three broad themes are used: terminal illness issues such as post-death existence and existential meaning of life, religious disenfranchisement from society or families of origin, and multicultural spiritual and religious issues. Practical recommendations for counselors and research implications are included.     

A tactile stimulation device for measuring two-point and gap discrimination thresholds in humans

A device to measure two-point-discrimination and gap-discrimination thresholds is described. The apparatus is capable of controlled and reliable delivery of forces up to 42.50 g while determining point of skin contact and subsequent depth of skin indentation during threshold determination. Stimulus delivery is controlled by computer software that deactivates a solenoid, allowing a counterbalanced beam with one of two stimulus wheels mounted on its end to rise and stimulate the skin. Depth of skin indentation is recorded by hardware that monitors the output of a photocell reflecting the position of the beam. The apparatus allows complete computer control of all data acquisition and recording.     

Congruence couple therapy for alcohol use and gambling disorders with comorbidities (part I): Outcomes from a randomized controlled trial

A nonblinded randomized trial was conducted at two Canadian provincial outpatient addiction clinics that tested the effectiveness of a systemic congruence couple therapy (CCT) versus individual-based treatment-as-usual (TAU) on nine clinical outcomes: (1) primary outcomes—alcohol use and gambling, psychiatric symptoms, and couple adjustment; (2) secondary outcomes—emotion regulation, substance use, depression, post-traumatic stress symptoms, and life stress. Data of primary clients and partners (N = 46) were analyzed longitudinally across baseline, posttreatment (5 months), and follow-up (8 months). Alcohol use disorder (95%) and gambling disorder (5%) were in the severe range at baseline, and co-addiction was 27%. Psychiatric comorbidity was 100%, and 18% of couples were jointly addicted. Between-group comparison favored CCT in primary outcomes with medium-to-large effect sizes (Cohen's h = 0.74–1.44). Secondary outcomes were also significantly stronger for CCT (Cohen's h = 0.27–1.53). Within-group, for all primary outcomes, a significant proportion of symptomatic CCT clients and partners improved, converging with ANOVA results of large effect sizes (0.14–0.29). All secondary outcomes improved significantly in CCT with large effect sizes (0.14–0.50). TAU showed significant within-group improvement in alcohol use, other substance use, and life stress with large effect sizes (0.16–0.40). Primary clients and partners made largely equivalent improvement within CCT and within TAU. Results were triangulated with clients' satisfaction ratings and counselors' reports. Overall, significant within-group effects were detected for CCT both clinically and statistically and between-group difference favored CCT. Future trials are required to validate these promising findings.     

Examining the influence of group diversity on the functioning of community-based participatory research partnerships: A mixed methods study

Public health has endorsed the use of community-based participatory research (CBPR) to address health inequities involving diverse and marginalized communities. However, few studies have examined how group diversity among members of CBPR partnerships influenced how well the partnerships achieve their goals of addressing health inequities through equitable collaboration. We conducted secondary, convergent, mixed methods analysis to (1) evaluate the association between group diversity and participatory decision-making within CBPR partnerships, and (2) identify the perceived characteristics, benefits, and challenges of group diversity within CBPR partnerships. Using data from a cross-site study of federally funded CBPR partnerships, we analyzed and integrated data from surveys of 163 partnerships (n = 448 partners) and seven in-depth case study interviews (n = 55 partners). Quantitatively, none of the measured characteristics of group diversity was associated with participatory decision-making within the partnerships. Qualitatively, we found that partnerships mainly benefited from membership differences in functional characteristics (e.g., skillset) but faced challenges from membership differences in sociocultural characteristics (e.g., gender and race). The integrated findings suggest the need to further understand how emergent group characteristics and how practices that engage in group diversity contribute to collective functioning of the partnerships. Attention to this area can help promote health equity achievements of CBPR partnerships.     

When to intervene and take a stand: Evaluating bystander roles in intergroup name-calling contexts

Children (n = 121, M = 9.86 years, SD = 0.64) and adolescents (n = 101, M = 12.84 years, SD = 0.69) evaluated proactive and passive bystander behaviour to intergroup name-calling (N = 222, 54% female). Scenarios depicted ingroup perpetrators and outgroup victims who were from a stigmatized group (ethnicity) or a non-stigmatized group (school affiliation), with bystanders depicted as being proactive (intervening to help) or passive (failing to challenge the aggression), counter to their own group's norm. Children and adolescents personally evaluated proactive bystanders more favourably than passive bystanders. However, adolescents, more than children, expected their peers to be more positive about proactive bystanders than passive bystanders in the stigmatized context. Results are discussed in terms of the complexities of bystander decisions and implications for anti-bullying interventions.     

Contributions of qualitative research to the validity of intervention research

The Interdisciplinary Qualitative Research Subcommittee (IQRS) of the Task for on Evidence-based Interventions in School Psychology assumed the responsibility of developing criteria for reviewing qualitative methods used in intervention research. The IQRS, composed primarily of psychologists and anthropologists, was confronted with the long-standing debate between qualitative and quantitative researchers and with the task of explicating the potential contributions of qualitative research to establishing an evidence base for interventions in school psychology. Consequently, the outcomes of the subcommittee's work included not only a set of criteria for evaluating qualitative research but also a clearer understanding of the added value of mixed qualitative-quantitative approaches to intervention research. The purposes of this article are to provide an overview of qualitative research, present the criteria set forth by the IQRS, discuss the role of qualitative research in establishing the foundation for evidence-based practice, and introduce the illustrative research articles of the special issue. The four studies highlighted in this issue represent applications of qualitative research that meet the IQRS criteria and demonstrate the potential of qualitative research, conducted within a mixed-method framework, for enhancing our understanding of school-based interventions.
