Youth attitudes toward guns and violence: relations with sex, age, ethnic group, and firearm exposure.

Investigated relations between young people's scores on the Attitudes Toward Guns and Violence Questionnaire (AGVQ; Shapiro, Dorman, Burkey, Welker, & Clough, 1997), demographic variables, and exposure to firearms and violence. 1,164 students, Grades 3 to 12, from an urban, suburban, parochial, and private school system completed anonymous self-report questionnaires in their classrooms. Boys produced higher AGVQ scores than did girls. Scores were similar in Grades 3 and 5, were much higher in Grade 6 than in Grade 5, and were similar in Grades 6 and above. This pattern was found across sex, race, and school system. African Americans obtained higher scores than Caucasians on the AGVQ and on 2 of its 4 factors. Students in the urban public schools produced higher scores than did youth in the other school systems. Both traumatic and nontraumatic exposure to firearms were associated with high AGVQ scores. Sex, grade, and firearm exposure were associated with relatively large differences, while ethnic group and school system were associated with relatively small differences.

The Youth Client Satisfaction Questionnaire: development, construct validation, and factor structure.

Developed and pilot-tested a measure of satisfaction with mental health services for young clients. One hundred fifty youth from 11 to 17 years of age who had completed services received the measure as a telephone interview. Fourteen of 17 candidate items met criteria for test-retest reliability, part-whole correlation, and correlation with a validation item, and they were retained in the instrument. Total score test-retest reliability and internal consistency were highly satisfactory. Principal components analysis revealed two factors, labeled Relationship With Therapist and Benefits of Therapy. Unexpectedly, satisfaction scores were not related to change in youth self-reported behavior problems. However, convergent validity was indicated by significant relationships with change in parent-reported behavior problems, parent satisfaction, parent ratings of treatment progress, therapist ratings of progress, and Global Assessment of Functioning change scores. These results indicate that the Youth Client Satisfaction Questionnaire is a reliable and valid measure of consumer evaluations of their treatment.

Development and factor analysis of a measure of youth attitudes toward guns and violence.

Administered the Attitudes Toward Guns and Violence Questionnaire (AGVQ) to 1,619 students in Grades 3, 5, 6, 7, 9, 11, and 12 from four demographically diverse school systems. Fifty-two of the 61 items exhibited satisfactory part-whole correlation and correlation with a validity criterion. Factor analysis revealed four main factors: Aggressive Response to Shame, Comfort With Aggression, Excitement, and Power/Safety. The instrument was reduced to 23 items by deleting items with high cross-loadings. Construct validity was similar for the longer and shorter versions. Youth who self-reported owning a gun produced scores 1.5 SD higher than nonowners. Low scores were associated with a 1 in 125 chance of gun ownership, and high scores were associated with a 1 in 3 chance. Congruency coefficients indicated similar factor structure for the present sample and a separate sample of 5th-, 7th- and 9th-grade students. These results indicate that the AGVQ is a reliable and valid measure of violence-related attitudes in young people.

A naturalistic study of psychotherapeutic methods and client in-therapy functioning in a child community setting.

Utilized a naturalistic methodology to examine treatment responses associated with major psychotherapeutic methods in 150 youth aged 11 to 17 years old in a community mental health center. Treatment methods were not experimentally controlled but were measured retrospectively by therapist report. Treatment response was assessed by a composite of 6 measures completed by clients, parents, and therapists. Pretest/posttest comparisons indicated improved functioning in the sample as a whole. Treatment response was not related to the proportion of therapy using individual, family, or group modalities. Therapy response was positively associated with extent of use of cognitive therapy. Social skills training, behavior therapy, and family systems therapy were associated with more positive treatment response in some subgroups of clients. The number of approaches used in an individual case (technical eclecticism) was positively related to client response. Treatment response was more consistently related to level of client and parent functioning in therapy than to treatment method.
