Both internalizing and externalizing psychopathologies interfere with the treatment of substance use disorders (SUD) in adolescents. Self-reports of psychopathologies are likely biased and may be validated with parental reports. We compared N = 70 standardized self-reports of adolescents entering outpatient SUD treatment (13.2–18.6 years old, 43% female) to parental reports on the same psychopathologies, and explored biases due to gender, age, SUD diagnoses and SUD severity. Bivariate bootstrapped Pearson correlation coefficients revealed several small to moderate correlations between both reporting sources (r = 0.29–0.49, all p_corrected ≤ 0.039). A repeated measures MANOVA revealed moderately stronger parental reports of adolescent psychopathologies compared to adolescent self-reports for most externalizing problems (dissocial and aggressive behaviors, p ≤ 0.016, η²_part = 0.09–0.12) and social/attention problems (p ≤ 0.012, η²_part = 0.10), but no differences for most internalizing problems (p ≥ 0.073, η²_part = 0.02–0.05). Differences were not associated with other patient or parental characteristics including age, gender, number of co-occurring diagnoses or presence/absence of a certain SUD (all p_uncorrected ≥ 0.088). We concluded that treatment-seeking German adolescents with SUD present with a multitude of extensive psychopathologies. The relevant deviation between self- and parental reports indicate that the combination of both reports might help to counteract dissimulation and other reporting biases. The generalizability of results to inpatients, psychiatry patients in general, or adolescents without SUD, as well as the validity of self- and parental reports in comparison to clinical judgements remain unknown.

内化和外化精神病理学都会干扰青少年物质使用障碍 (SUD) 的治疗。精神病理学的自我报告可能有偏见，可以通过父母的报告进行验证。我们将N  = 70 名接受门诊 SUD 治疗的青少年标准化自我报告（13.2-18.6 岁，43% 为女性）与父母关于相同精神病理学的报告进行了比较，并探讨了由于性别、年龄、SUD 诊断和 SUD 严重程度而导致的偏差。双变量自举 Pearson 相关系数揭示了两个报告来源之间的几个小到中等的相关性（r  = 0.29–0.49，所有p_已校正 ≤ 0.039)。重复测量 MANOVA 显示，与大多数外化问题（社交和攻击行为，p  ≤ 0.016，η2^部分 = 0.09-0.12）和社交/注意力问题（p ≤ _0.012  ，η ²_部分 = 0.10)，但大多数内化问题没有差异（p  ≥ 0.073，η ²_部分 = 0.02–0.05）。差异与其他患者或父母特征无关，包括年龄、性别、同时诊断的数量或是否存在某种 SUD（所有p_未校正 ≥ 0.088)。我们的结论是，寻求治疗的患有 SUD 的德国青少年存在多种广泛的精神病理学。自我报告和父母报告之间的相关偏差表明，两种报告的结合可能有助于抵消掩饰和其他报告偏差。结果对住院患者、一般精神病患者或没有 SUD 的青少年的普遍性，以及自我和父母报告与临床判断相比的有效性仍然未知。
