The Strengths and Difficulties Questionnaire (SDQ) is widely used, based on evidence of its value for screening. This evidence primarily regards the single informant total difficulties scale and separate difficulties subscales. We assessed to what degree adolescents' SDQ profiles that combined all self- and parent-rated subscales were associated with use of care and psychiatric diagnoses, and examined the added value thereof over using only a single informant and the total scale. Cluster analysis was used to identify common SDQ profiles based on self- and parent-reports among adolescents aged 12-17 in mental healthcare (n = 4282), social care (n = 124), and the general population (n = 1293). We investigated associations of the profiles with 'care use' and 'DSM-IV diagnoses', depending on gender. We identified six common SDQ profiles: five profiles with varying types and severities of reported difficulties, pertaining to 95% of adolescents in care, and one without difficulties, pertaining to 55% of adolescents not in care. The types of reported difficulties in the profiles matched DSM-IV diagnoses for 88% of the diagnosed adolescents. The SDQ profiles were found to be more useful for predicting care use and diagnoses than SDQ scores reported by the adolescent as single informant and the total difficulties scale. The latter indicated the presence of problems among 42-63% of the adolescents in care, missing a substantial number of adolescents with reported emotional difficulties and borderline problem severity. These findings advocate the use of combined self- and parent-rated SDQ score profiles for screening.
《长处与困难问卷》（SDQ）应用广泛，其价值已得到充分验证，可用于筛查。这些证据主要涉及单一信息源的总困难量表和单独的困难分量表。我们评估了综合所有自我报告和家长报告的子量表的青少年 SDQ 特征与使用护理和精神科诊断的关联程度，并检验了其相对于仅使用单一信息源和总量表的附加价值。聚类分析用于根据精神卫生保健（n=4282）、社会保健（n=124）和一般人群（n=1293）中 12-17 岁青少年的自我报告和家长报告，识别 SDQ 特征。我们根据性别调查了这些特征与“护理使用”和“DSM-IV 诊断”的关联。我们确定了六个常见的 SDQ 特征：五个具有不同类型和严重程度报告困难的特征，涉及护理中的 95%的青少年，一个没有困难的特征，涉及未接受护理的 55%的青少年。在这些特征中报告的困难类型与 DSM-IV 诊断相符，占诊断青少年的 88%。研究发现，与青少年作为单一信息源和总困难量表报告的 SDQ 得分相比，SDQ 特征更有助于预测护理使用和诊断。后者表明，在接受护理的青少年中，42%-63%存在问题，错过了相当数量报告有情绪困难和边缘问题严重程度的青少年。这些发现提倡使用综合自我和家长评定的 SDQ 评分特征进行筛查。
