An investigation of the validity of the SPSI and SPSI-R in differentiating high-suicidal from depressed,low-suicidal college students

The present study examined the validity of the Social Problem-Solving Inventory (SPSI) and SPSI—Revised in differentiating 65 high-suicidal from 63 depressed, low-suicidal college students. Results from multivariate analyses indicated overall differences in problem-solving between these two groups as measured by the SPSI but not by the SPSI-R. Further examination of these differences revealed the high-suicidal group was different in problem-solving orientation, rather than problem-solving skills, compared to the depressed, low-suicidal group. However, when depression was statistically controlled in hierarchical regression analyses, none of the problem-solving measures predicted group membership. The superiority of the SPSI to the SPSI-R in differentiating these two groups appears to be accounted for by the elimination of 28 items in the revised version, many of which measure orientation to problem-solving. Also explored was the possibility that objective measures of problem-solving provide a better prediction of adjustment than do self-report measures.     

Permanence and change in memory II. Reproduction of words in sentences

Abstract.— A retroactive interference paradigm was employed for studying qualitative memory changes. Sentences, containing an ambiguous word that was defined differently by succeeding words, were used as stimulus material. Such retroactive definitions of meaning were found to lead to qualitative changes in reproduction. It is suggested that the issue of permanence and change in memory may be related to the choice of lists of independent items or contextual units as stimulus material. A contextual theory of memory, implying the conception of memory in a stream, is advocated.     

How Discrimination Impacts Sociopolitical Behavior: A Multidimensional Perspective

The conventional wisdom regarding the impact of discrimination on political behavior is that the perception of prejudiced treatment motivates individuals to take political action. This study challenges this common conception by demonstrating that the source of discrimination can play a significant role in whether perceived or experienced injustice leads to activism or withdrawal from sociopolitical life. Drawing from political science and social psychology literature, this study provides a new perspective on the potential effects of discrimination on a relatively new marginalized group in the United States. Specifically, an important distinction is drawn between political (systematic) and societal (interpersonal) discrimination in analyzing the sociopolitical behavior of American Muslims in the aftermath of the 9/11 terrorist attacks. The results will hopefully encourage scholars to take a deeper look at the nexus between discrimination and democratic engagement, which is an important, complex, multidimensional, and understudied topic.     

Stress,social support,and problem-solving appraisal/skills: Prediction of suicide severity within a college sample

This study assessed whether stress, social support, and interpersonal problem-solving appraisal/skills were predictive of level of suicidality within a chronic suicidal college sample. Stepwise regression analyses were used to assess whether stress, social support, and problem-solving were independently predictive of severity of suicide ideation. In addition, hierarchical regression analyses were used to test the mediational nature of social support and problem-solving in the stress-suicidality relationship. Problem-solving confidence was found to be a significant predictor of severity of suicide ideation. In addition, both perceived problem-solving skills and social support mediated the relationship between stress and level of suicide ideation. However, only one of the two perceived problem-solving skills interactions was in the expected direction. This study provided support for the importance of problem-solving confidence and the interaction of stress and social support in the prediction of suicide severity. Unlike previous studies, this study did not find problem-solving skills/deficits to mediate the stress-suicidality relationship.This research was supported by NIMH Grant 1-18MH48133.     

An expanded etiological model for suicide behavior in adolescents: Evidence for its specificity relative to depression

This study tests both the stress/social support and the stress/problem-solving etiological models for suicidality while controlling for depression. To this end, a depressed, high-suicide-ideating sample (N=68) was compared to a depressed, low-suicide-ideating sample (N=64). Hierarchical multiple regression analyses were used to test the unique contributions of stress, problem-solving orientation, problem-solving skills, and perceived level of social support in predicting level of suicidality. Hierarchical regression analyses were also used to test the interactive contributions of problem-solving × stress and social support × stress in predicting level of suicidality. Regression models were generated separately for men, women, and the entire sample using all factors. The results clearly support the importance of social support as an independent predictor of suicidality for men, women, and the entire sample. Ability to generate alternatives to identified problems predicted suicidality, but only for women and the entire sample. Problem-solving orientation was not uniquely predictive of suicidality and may affect suicidal behavior via its relationship to depression.     

A dimensional analysis of claustrophobia

The present study investigated whether situational and cognitive dimensions of claustrophobia exist. To this end, the Claustrophobia Situations Questionnaire (CSQ) and the Claustrophobia General Cognitions Questionnaire (CGCQ) were developed and exploratory factor analyses were performed on these scales. Two-factor solutions for both the anxiety and the avoidance ratings on the CSQ were obtained, accounting for 40.1% and 34.2% of the variance, respectively. Two subscales were created from the two-factor solution of the anxiety section of the CSQ: (1) Fear of Entrapment and (2) Fear of Physical Confinement. Two subscales were also created from the two-factor solution of the avoidance section of the CSQ: (1) Avoidance of Crowds and (2) Avoidance of Physical Confinement. A three-factor solution was obtained for the CGCQ, accounting for 54.4% of the variance, from which the following three subscales were created: (1) Fear of Loss of Control, (2) Fear of Suffocation, and (3) Fear of Inability to Escape. Cronbach alphas for all subscales ranged from .84 to .94. Exploratory correlational analyses were conducted between the situational and the cognitive dimensions.
