目的：本研究的目的是开发和验证一种筛查工具，用于初级保健中发现有未来暴力犯罪风险的青少年。方法165名11-17岁的青少年在初级保健预约期间入组。两个诊所作为研究地点。青少年在基线和1年随访期间秘密填写问卷。主要结果是前一年的暴力行为。在基线上，青少年回答了18个预测未来暴力参与的风险和保护因素问题。额外的暴力量表共有47个问题。项目分析确定了哪种组合最能预测未来的暴力行为。心理测量特性包括内部一致性、重测信度、收敛效度和预测效度。结果共有101名青少年（61%）完成了1年的随访：16%的青少年报告有暴力行为，性别和种族/民族无差异。25个基线问题与一年后的暴力行为相关。经项目分析，14个问题表现出最强的心理测量功能，Cronbach’s α = .77。外部效度较强，14项暴力伤害保护和风险筛查与攻击量表（0.74）和受害量表（0.54）相关，与力量与困难问卷（0.54）相关。39)和当前的暴力参与（0.78）。对于14-17岁的青少年，预测效度与未来的暴力行为密切相关（0.78）。男性5.0分，女性6.0分，敏感性为77%，特异性为98%，阳性预测值为91%。在14-17岁的青少年中，有17%的人使用这些临界值进行了筛查。结论一份简短的14项问卷具有较强的心理测量功能，可作为预测14-17岁青少年未来暴力行为的筛选工具。
PURPOSEThe aim of this study was to develop and validate a screening tool to detect youth at risk for future violence perpetration for primary care.METHODSYouth (n = 165) aged 11–17 years enrolled during a primary care appointment. Two clinics served as study sites. Youth filled out questionnaires confidentially at baseline and at 1-year follow-up. Primary outcome was violent behavior during the preceding year. At baseline, youth answered 18 risk and protective factor questions that predicted future violence involvement. Additional violence scales were asked for a total of 47 questions. Item analysis determined which combination best predicted future violence involvement. Psychometric properties, including internal consistency, test–retest reliability, convergent validity, and predictive validity, were analyzed.RESULTSA total of 101 youth (61%) completed 1-year follow-up: 16% reported violent behavior with no difference between gender or race/ethnicity. Twenty-five baseline questions correlated with violence involvement 1 year later. After item analysis, 14 questions demonstrated the strongest psychometric functioning with Cronbach's α = .77. External validity was strong, with the 14 item violence injury protection and risk screen correlating with the aggression (.74) and victimization (.54) scales, the Strength and Difficulties Questionnaire (.39), and current violence involvement (.78). For youth aged 14–17 years, predictive validity was strongly correlated (.78) with future violence perpetration. A score of 5.0 for males and 6.0 for females revealed a sensitivity of 77%, a specificity of 98%, and a positive predictive value of 91%. Seventeen percent of youth aged 14–17 screened positive using these cutpoints.CONCLUSIONA brief, 14-item questionnaire demonstrated strong psychometric functioning and performed well as a screening tool to predict future violence perpetration for youth aged 14–17.
