A Comparison of the Psychometric Properties of Three Measures of Dietary Restraint.

A subscale of the Three-Factor Eating Questionnaire (TFEQ), a subscale of the Dutch Eating Behavior Questionnaire (DEBQ), and the Revised Restraint Scale (RS) were administered to 90 1 undergraduates. Test-retest reliability (on 34 subjects) was highest for the RS (r =.95) and roughly equal for the DEBQ (r =.92) and the TFEQ (r =.91). Internal consistency was highest for the DEBQ (α =.95), moderate for the TFEQ (α =.90), and lowest for the RS (α =.82). The DEBQ was the most homogeneous scale, with a single principal component accounting for 68.2% of the variance

Calculating effect sizes for meta-analysis: The case of the single case∗

This paper reviews methods for deriving measures of effect for interrupted time-series (single case) designs. Limitations of prior models are described. Modifications of a regression approach developed by Center, Skiba, and Casey (1985-86, Journal of Special Education, 19, 387-400) which can simultaneously account for treatment effects on level and slope while controlling for effects of trend are advocated and a step-by-step computational algorithm is provided. The primary modification entails computing the initial estimate of trend only on baseline data. Implementation of the method with various forms of single case designs is described.

The extended satisfaction with life scale: Development and psychometric properties

The development and psychometric properties of the Extended Satisfaction With Life Scale (ESWLS) are described in detail. The ESWLS is a 50-item self-report scale that measures satisfaction with life in nine domains. It can be completed by most people in under 20 minutes and can be used by researchers and clinicians. The readability of the ESWLS was estimated to be between the seventh and tenth grade levels. Internal consistency, estimated by coefficient α, ranged from 0.81 to 0.96 for the individual subscales. Two-week test-retest reliability coefficients ranged from 0.74 to 0.87. Results of exploratory and confirmatory factor analyses strongly supported the factor structure of the ESWLS. Preliminary evidence of convergent and discriminant validity is provided as well as preliminary norms.

Stigmatization and suicide bereavement.

With survey data collected primarily from peer support group participants, the authors compared stigmatization responses of 462 parents losing children to suicide with 54 other traumatic death survivors and 24 child natural death survivors. Parents who encountered harmful responses and strained relations with family members and non-kin reported heightened grief difficulties. After controlling for time since the death and whether a childs death was traumatic or not, stigmatization continued to be associated with grief difficulties, depression, and suicidal thinking. Suicide survivors reported little differences in stigmatization from other-traumatic-death survivors, a result consistent with other recent studies, suggesting more convergence between these two populations than divergence.

Internet support groups for suicide survivors: a new mode for gaining bereavement assistance

Taken among parents who sustained the loss of a child to suicide this study explores the participation of parents in Internet support groups, comparing their demographic and loss-related characteristics (N = 104) to other parent survivors participating in face-to-face support groups (N = 297). Contrary to expectations that Internet affiliates would be concentrated in under-served rural areas, we found similar levels of urban, suburban, small city and rural residents in both Internet and face-to-face subsamples. Bivariate and multivariate analyses suggested several important factors contributing to interest in Internet grief support including: 24/7 availability and opportunities to invest more time into this type of support group experience. Compared to their face-to-face group counterparts, Internet affiliates experienced greater suicide stigmatization from their families and other associates. Unable to find ready comfort and support from their personal communities, Internet users—and especially highly depressed survivors—sought and obtained valuable help from the Internet support resource.

Linking in-session change to overall outcome in short-term cognitive therapy.

To better understand the mechanisms of change in psychotherapy, it is important to validate suboutcome measures that represent intermediate links between more molecular in-session changes and ultimate outcome. The present study involved the collection of pre- and postsession ratings from 53 patients in a 20-session protocol of cognitive therapy, which yielded 5 suboutcome measures: Anxiety Shift, Depression Shift, Cognitive Shift, Optimism Shift, and Therapeutic Alliance. From a series of regression analyses of repeated measures with a generalized estimating equations approach, results regarding the predictive relationship of these variables to a number of patient and therapist-rated outcome criterion variables indicated that change in cognition and quality of the therapeutic alliance were the strongest predictors.

Sex and social representations of aggression: a communal-agentic analysis

Previous research [Campbell and Muncer: Journal for the Theory of Social Behavior 17: 489–512, 1987; Campbell et al.: Aggressive Behavior 18: 95–108, 1992] suggests that men and women hold different social representations or implicit theories of their own aggression. Men view it is an instrumental act (a means of obtaining and exercising power to gain social rewards), while women view it an expressive act (a cathartic discharge of anger). In the present study, communal/agentic personality styles and gender identity are examined as possible mediators of the relation between sex and Expaag–a psychometric measure of adherence to an expressive representation of aggression. In addition a measure of self-reported aggression is included. The highest correlation appeared between sex and Expaag. Gender identity and interpersonal style made no significant improvement in explained variance in a multiple regression analysis after sex had been entered. An instrumental social representation of aggression was significantly and positively correlated with number of reported aggressive acts.

How they died, time since loss, and bereavement outcomes

This analysis explores associations between differing death circumstances and the course of bereavement among a sample of 540 bereaved parents. Comparisons were made between parents whose children died by suicide (n = 462), those losing children from other traumatic death circumstances (n = 54), and others whose children died from natural causes (n = 24). Results were mixed, showing suicide survivors with more grief difficulties and other mental health problems on some criteria, though most findings showed no substantive differences between these subgroups. Results also showed, in the first years after loss, repeated suicide attempts and prior negative relationships with the decedent were associated with greater grief difficulties. However, as more time passed, all death circumstance differences were overshadowed by the importance of the time span since loss. This data also suggested that between 3 and 5 years usually marks the turning point, when acute grief difficulties accompanying a suicide loss begin to subside.

“Make things as simple as possible, but no simpler.” A rejoinder to Scruggs and Mastropieri

Scruggs and Mastropieri (Behaviour Research and Therapy, 32, 879–883, 1994) take issue with criticisms of their PND (Percent of Nonoverlapping Data) statistic that we offered in our recent article (Allison & German, Behaviour Research and Therapy, 31, 621–631, 1993), which advocated a regressionbased method for obtaining effect sizes in single-subject studies. They contend that their PND approach has several advantages over our approach because: (1) they believe that, unlike ours, it can take advantage of the small number of observations that are typically available in single-case studies; (2) it is simple to compute; (3) it frees researchers from traditional regression assumptions of normality, homogeneity of variance, and independence of observations and residuals; and (4) it correlates with visual judgements made by experts. As we shall argue, these claims are built upon very questionable assumptions and they are very difficult to substantiate. In addition, we show that the expected value of the PND is so strongly related to sample size as to be rendered meaningless.
