Evaluation of the situations related to heroin-taking, and the consequent delimitation and characterization of the patient's drug-taking pattern, should be one of the first stages in the design of an individualized treatment in the context of a cognitive-behavioural therapeutic approach. The Inventory of Drug-Taking Situations (Heroin) (IDTS[H]; Annis y Martin, 1985) was administered to a sample of 124 opiate dependent patients in order to study its reliability and factor structure. An Alpha reliability coefficient of .93 was obtained. A principal component analysis of the measure revealed a five-component solution which accounted for 50.6% of the variance. Nevertheless, a confirmatory factor analysis of the self-report showed that the original eight-factor model provides an acceptable fit to the data. Lastly, the frequency at which each of the eight original IDTS(H) subscales appeared as the highest risk situation in the profile was calculated, showing the predominance of Negative Emotional States (35%) and Social Pressure to Use (18%) as the two most important high-risk situations. Theoretical and clinical implications of the results are discussed.
在认知行为治疗方法的背景下，对与海洛因使用相关的情况进行评估，以及对患者吸毒模式进行相应的界定和特征描述，应该是个性化治疗设计的首要阶段之一。为了研究其信度和因子结构，对124名阿片类药物依赖患者的样本进行了《吸毒情境量表（海洛因）》（IDTS[H]；安妮斯和马丁，1985年）的施测。获得了0.93的阿尔法信度系数。对该量表的主成分分析揭示了一个五成分的解决方案，该方案解释了50.6%的方差。然而，对自我报告的验证性因子分析表明，最初的八因子模型与数据拟合良好。最后，计算了八个原始IDTS(H)子量表中每个子量表在概况中作为最高风险情况出现的频率，结果显示消极情绪状态（35%）和使用毒品的社会压力（18%）作为两个最重要的高风险情况占主导地位。讨论了结果的理论和临床意义。
