Three inter-related studies examine the construct of problem solving as it relates to the assessment of deficits in higher level outpatients with traumatic brain injury (TBI). Sixty-one persons with TBI and 58 uninjured participants completed measures of problem solving and conceptually related constructs, which included neuropsychological tests, self-report inventories, and roleplayed scenarios. In Study I, TBI and control groups performed with no significant differences on measures of memory, reasoning, and executive function, but medium to large between-group differences were found on timed attention tasks. The largest between-group differences were found on psychosocial and problem-solving self-report inventories. In Study II, significant-other (SO) ratings of patient functioning were consistent with patient self-report, and for both self-report and SO ratings of patient problem solving, there was a theoretically meaningful pattern of correlations with timed attention tasks. In Study III, a combination of self-report inventories that accurately distinguished between participants with and without TBI, even when cognitive tests scores were in the normal range, was determined. The findings reflect intrinsic differences in measurement approaches to the construct of problem solving and suggest the importance of using a multidimensional approach to assessment

(from the journal abstract) This paper examines the experiences of gay men living with disabilities or chronic illness from a social constructivist perspective. Emphasizing the sociocultural aspects of disability, such an approach recognizes that the questions asked and the answers given about disability are embedded in sociohistorical contexts, and that language both shapes and reveals underlying assumptions and behaviors related to disability. Using Kameny 's (1971) concept of sociological minority, it is proposed that gay men and persons with disabilities constitute minority groups with experiences in common with those of other recognized minority groups. Implications for mental health practitioners providing services to gay men with disabilities are addressed.

To enhance understanding of the role that social problem solving (SPS) plays in community integration following traumatic brain injury (TBI). Study Design: Regression analysis. Participants: Forty-five adults with TBI participating in higher level outpatient cognitive rehabilitation and 15 uninjured adults. Main Outcome Measures: Measures of community integration, problem-solving ability, and SPS self-appraisal and performance. Results: Individuals with TBI demonstrated poorer problem-solving as measured by both neuropsychological and SPS methods; however, the largest effect size was observed for SPS self-appraisal. Only SPS self-appraisal predicted a significant proportion of the variance in community integration. Conclusions: It is important to assess brain-injured persons' confidence in their ability to cope with problems. A focus on objective test scores alone may lead to underdetection of disabling problem-solving deficits.

Sixty higher-level outpatients with traumatic brain injury (TBI), all at least 1 year post-injury, were randomly assigned to either conventional group neuropsychological rehabilitation or an innovative group treatment focused on the treatment of problem-solving deficits. Incorporating strategies for addressing underlying emotional self-regulation and logical thinking/reasoning deficits, the innovative treatment is unique in its attention to both motivational, attitudinal, and affective processes and problem-solving skills in persons with TBI. Participants in the innovative group improved in problem solving as assessed using a variety of measures, including (1) executive function, (2) problem-solving self-appraisal, (3) self-appraised emotional self-regulation and clear thinking, and (4) objective observer ratings of roleplayed scenarios. These improvements were maintained at follow-up. Baseline performance on timed attention tasks was related to improvement; individuals who processed the most slowly benefited the most. These participants did not show improvements on timed attention tasks, but did improve on problem-solving measures. Such findings are consistent with successful compensatory strategy use-the person may still have deficits and symptoms, but now has effective strategies for reducing their impact on daily functioning.

OBJECTIVE: To compare the relative utility of conventional neuropsychological and social problem-solving approaches to measuring functional problem solving deficits in individuals with acquired brain damage (ABD). DESIGN: In Study I, scores for individuals with ABD were compared to scores for control and normative samples. In Study II, pre- and posttest scores were compared for individuals with ABD who completed a program of outpatient cognitive rehabilitation. PARTICIPANTS: In Study I, individuals with ABD were compared to healthy controls. In Study II, pre- and posttreatment assessments were obtained for 34 individuals with ABD. MAIN OUTCOME MEASURES: Two approaches were used, conventional neuropsychological (WAIS-R/II Comprehension subtest and Wisconsin Card Sorting Test) and social problem solving (Problem Solving Inventory and Rusk Problem Solving Role Play Test). RESULTS: In Study I, the ABD group demonstrated significant deficits on both social problem solving measures; however, neither conventional neuropsychological measure detected significant deficits in the ABD group, relative to control and normative groups. In Study II, significant treatment gains were demonstrated on both social problem-solving measures, however neither conventional neuropsychological measure was sensitive to improvements in functional problem-solving ability. CONCLUSIONS: In higher-level cognitive rehabilitation settings, the evaluation of functional problem-solving deficits in individuals with ABD can be facilitated by augmenting neuropsychological test data with results from social problem-solving measures
