The current study evaluated the construct validity and sensitivity to change of the Spectra: Indices of Psychopathology in an inpatient psychiatric sample (N = 83). Admission diagnoses were generally split between Depression / Anxiety (27.7%), Substance Use Disorders (27.7%), Bipolar Disorder (22.9%), and Primary Psychotic Disorders (21.7%). Results indicate the three higher-order spectra scores (Internalizing, Externalizing, and Reality Impairing) effectively differentiated between known clinical groups, with effect sizes (η_p²) ranging from 0.13 (Internalizing) to 0.44 (Externalizing). Hypothesized spectra scores also discriminated between groups with and without a history of suicide attempts (Internalizing Cohen’s d = 0.60), arrests within the last five years (Externalizing Cohen’s d = 0.60), and a primary psychotic disorder diagnosis at admission (Reality Impairing Cohen’s d = 1.12). Concurrent validity was supported when examining patterns of correlations with the Personality Assessment Inventory; all target correlations were statistically significant (p < 0.05) and ranged from r = 0.36 (Psychotic Experience) to r = 0.76 (Depression). Finally, sensitivity to change assumptions were met when comparing admission and discharge scores for the subsample (N = 47) of patients who also completed the instrument at discharge. The implications with respect to application and clinical utility in acute (inpatient) settings are discussed.

当前的研究评估了构建体的有效性和对光谱变化的敏感性：住院精神病学样本中的精神病理学指标（N  = 83）。入院诊断通常分为抑郁/焦虑（27.7％），药物使用障碍（27.7％），双相情感障碍（22.9％）和原发性精神病（21.7％）。结果表明三个高阶谱得分（内部化，外化，与现实妨害）有效地分化已知的临床组之间，以作用大小（η _p ²）范围从0.13（内化）到0.44（外化）。虚拟化的谱得分也可以区分是否有自杀未遂史（Inhenizing Cohen's d）。 = 0.60），最近五年内被捕（外部化Cohen d  = 0.60）和入院时的原发性精神病诊断（现实障碍Cohen d  = 1.12）。当检查与人格评估量表的相关模式时，支持并发效度; 所有目标相关性均具有统计学意义（p  <0.05），范围从r  = 0.36（精神病经验）到r  = 0.76（抑郁）。最后，在比较子样本的入学分数和出院分数时，满足了对变化假设的敏感性（N = 47）在出院时也完成了仪器的患者。讨论了有关在急性（住院）环境中的应用和临床效用的含义。
