Validation of Self-Report Measures of Emotional and Physical Distress Tolerance

The Distress Tolerance Scale (DTS) and Discomfort Intolerance Scale (DIS) are self-report measures developed for the assessment of emotional and physical distress tolerance, respectively. However, little evidence exists for their construct and specifically criterion-related validity. The current study examined the associations of these self-report measures with lab-based assessments of perceived emotional tolerance and physical discomfort tolerance. Undergraduate participants (N?=?166) were administered four film clips intended to induce sadness, disgust, fear, and anger, and a handgrip persistence task intended to elicit physical discomfort. The DTS, but not the DIS, was significantly associated with self-reported emotional tolerance and perceived threat associated with each film after controlling for emotional intensity. Among DTS subscales, the absorption subscale was the only subscale incrementally predictive of negative perceptions of the sad film, the appraisal subscale was incrementally predictive of negative perceptions of the other three films, and little support for the incremental validity of the tolerance and regulation subscales was found. The DTS also incrementally predicted tolerance and perceived threat of film-elicited emotions across films after controlling for anxiety sensitivity. The DIS was only marginally predictive of handgrip task persistence and was unrelated to emotional film perceptions. Overall, these findings uniquely add to the empirical literature on the construct and criterion-related validity of the DTS and DIS.     

A comparison of multiple versus single examples of the correct stimulus on task acquisition and generalization by persons with developmental disabilities

In teaching discriminations to persons with retardation, we often presume we will improve acquisition and generalization if we use multiple examples of boththe correct and incorrect stimuli. Two experiments were conducted to test this hypothesis. In the first experiment, 7 persons with moderate retardation learned to discriminate between functional words under two conditions. In one condition, Multiple Example of S- Only,1 example of the correct stimulus (S+) and 10 examples of the incorrect stimulus (S-) were used during acquisition. In the other condition, Multiple Examples of S+ and S-,10 examples of the S+ and 10 examples of the S- were used. Results showed that the condition which presented only a single example of S+ was superior 16 times and inferior 4 times during acquisition, generalization, and maintenance. A second experiment was conducted to (a) replicate the methodology and procedures in Experiment 1 with different participants, (b) determine whether the results were replicable, and (c) obtain efficiency data. Results replicated the findings of the first experiment. The condition which presented only a single example of S+ was superior on measures of (a) trials to criterion, (b) percent correct during acquisition, and (c) minutes to criterion. On measures of generalization, the two conditions were relatively equal. Thus, the condition which presented only a single example of the correct stimulus was more efficient and was just as effective in generalization as the condition which presented multiple examples of both the S+ and S-. These surprising results were discussed in terms of stimulus control, why students performed just as well during generalization when only one example of the S+ was used, why acquisition was also poorer for this condition, and how future studies might address these points.     

A Windows program to assist in preparing reports of emergency psychiatry nursing assessments

The Emergency Psychiatry Nursing Assessment Report Framework (EP Nurse) is designed to guide the nurse through the interview-and-reporting process, and to produce a report of the nursing evaluation in emergency psychiatry in 5–10 min. Input includes identifying information, presenting complaints, substance-use history, medical history and vitals, psychiatric medications, treatment history, history of mental illness, last hospitalization, family history of mental illness, nursing diagnosis, and nursing intervention. EP Nurse is intended to be used by licensed nurses familiar with nursing assessment in emergency psychiatry. It is suitable for adult patients.     

Predictors of Symptom Outcome in Interpretation Bias Modification for Dysphoria

Interpretation Bias Modification (IBM) interventions have been effective in reducing negative interpretation biases theorized to underlie depressive psychopathology. Although these programs have been highlighted as potential short-term interventions for depression, mixed evidence has been found for their effects on depressive symptoms. There is a need to examine attitudes towards training as well as individual difference factors that may impact symptom outcomes for IBM depression interventions. Seventy-two dysphoric young adults were randomly assigned to receive either an IBM targeting negative interpretation bias in personal evaluations or interpersonal situations or a healthy video control (HVC) condition. Compared to those who received HVC, participants in the IBM condition reported lower negative interpretation bias at posttreatment. No differences between conditions were found for symptom outcomes. Greater perceived treatment credibility and expectancy were associated with better treatment outcomes for both the IBM and HVC groups. Within the IBM group, a greater tendency toward assimilation with treatment scenarios was significantly associated with better treatment outcomes for both depressive and anger symptoms. This effect was unique from treatment credibility and expectancy. Pretreatment psychological reactance did not predict treatment response for either condition. Implications and future research directions are discussed.     

Clarifying relationships among work and family social support, stressors, and work-family conflict

Although work and family social support predict role stressors and work-family conflict, there has been much ambiguity regarding the conceptual relationships among these constructs. Using path analysis on meta-analytically derived validity coefficients (528 effect sizes from 156 samples), we compare three models to address these concerns and clarify relationships. Results revealed that social support, controlling for role involvement, is best viewed as an antecedent of role stressors and subsequent work-family conflict. Controlling for work and family involvement, work and family social support were most related to same domain role conflict (β = −.46, p < .05; β = −.43, p < .05) and role ambiguity (β = −.28, p < .05; β = −.33, p < .05). Subsequently, work role conflict and time demands were most related to work-to-family conflict (β = .39, p < .05; β = .21, p < .05), while family role conflict and role ambiguity were most related to family-to-work conflict (β = .22, p < .05; β = .24, p < .05). Implications for research and practice, along with suggestions for theoretical advances, are discussed.     

Quantity judgments and individuation: evidence that mass nouns count

Three experiments explored the semantics of the mass-count distinction in young children and adults. In Experiments 1 and 2, the quantity judgments of participants provided evidence that some mass nouns refer to individuals, as such. Participants judged one large portion of stuff to be "more" than three tiny portions for substance-mass nouns (e.g. mustard, ketchup), but chose according to number for count nouns (e.g. shoes, candles) and object-mass nouns (e.g. furniture, jewelry). These results suggest that some mass nouns quantify over individuals, and that therefore reference to individuals does not distinguish count nouns from mass nouns. Thus, Experiments 1 and 2 failed to support the hypothesis that there exist one-to-one mappings between mass-count syntax and semantics for either adults or young children. In Experiment 3, it was found that for mass-count flexible terms (e.g. string, stone) participants based quantity judgments on number when the terms were used with count syntax, but on total amount of stuff when used with mass syntax. Apparently, the presence of discrete physical objects in a scene (e.g. stones) is not sufficient to permit quantity judgments based on number. It is proposed that object-mass nouns (e.g. furniture) can be used to refer to individuals due to lexically specified grammatical features that normally occur in count syntax. Also, we suggest that children learning language parse words that refer to individuals as count nouns unless given morpho-syntactic and referential evidence to the contrary, in which case object-mass nouns are acquired.     

A comparative test of work-family conflict models and critical examination of work-family linkages

This paper is a comprehensive meta-analysis of over 20 years of work-family conflict research. A series of path analyses were conducted to compare and contrast existing work-family conflict models, as well as a new model we developed which integrates and synthesizes current work-family theory and research. This new model accounted for 40% of the variance in job satisfaction, 38% of the variance in family satisfaction, and 35% of the variance in life satisfaction. In a critical examination of work-family linkages, a series of analyses excluding work-family conflict constructs and pathways resulted in a well-fitting and more parsimonious model that still accounted for 39% of the variance in job satisfaction, 37% of the variance in family satisfaction, and 33% of the variance in life satisfaction. Results indicate that direct effects drive work-family conflict models while indirect effects provide little incremental explanation in regards to satisfaction outcomes.     

Concerning the Preservation of God’s Omnipotence

Numerous examples have been offered that purportedly show that God cannot be omnipotent. I argue that a common response to such examples (i.e., that failure to do the impossible does not indicate a lack of power) does not preserve God’s omnipotence in the face of some of these examples. I consider another possible strategy for preserving God’s omnipotence in the face of these examples and find it wanting.
