本研究评估了行为健康问卷-20 （BHQ-20）的4个量表：整体心理健康、幸福感、症状和生活功能的心理测量特性。采用社区成人、大学生、大学生心理咨询和成人门诊心理治疗4个样本。内部一致性和2周重测信度得到支持。对于结构效度，BHQ-20量表在样本中区分病理水平，并且对3个心理治疗疗程的改善敏感。与已建立的测量量表的并发效度相关性至少中等高。还发现BHQ-20量表与已建立措施的非类似量表之间存在较高的相关性。这些结果，以及BHQ-20量表之间的高度相关性，表明存在一个主要的心理健康维度来解释方差。BHQ-20被证明是一份总体上可靠、有效的问卷，其特点是评估心理健康的效率高。
This study evaluated the psychometric properties of the 4 scales of the Behavioral Health Questionnaire-20 (BHQ-20): Global Mental Health, Well-Being, Symptoms, and Life Functioning. Four samples were used: community adults, college students, college students in counseling, and adults in outpatient psychotherapy. Support was found for internal consistency and 2-week test-retest reliability. For construct validity, the BHQ-20 scales distinguished levels of pathology among the samples and were sensitive to improvement across 3 psychotherapy sessions. Concurrent validity correlations with the scales of established measures were at least moderately high. Higher correlations were also found between the BHQ-20 scales and the nonanalogous scales of the established measures. These results, along with high correlations among the BHQ-20 scales, indicated the presence of 1 primary mental health dimension accounting for the variance. The BHQ-20 was proven to be a generally reliable, valid questionnaire that is distinguished by the efficiency with which it assesses mental health.
