As clinical psychology services to primary care have grown considerably in recent years, several papers have examined the impact of such services. Benefits to patients following contact with the psychologist have been described, but the few studies which have used control groups have -not shown long-lasting effects. However, assessing the global effects of psychological treatment creates several methodological problems, and many of the studies have serious shortcomings in their use of sampling procedures and dependent measures. Clear results are unlikely to emerge from such studies because psychological treatment is not a single entity but encompasses a number of interventions for different types of problem. A more differentiated approach to evaluation is needed to assess the effectiveness of psychological treatment services in primary care.
近年来，随着初级保健领域临床心理学服务的显著增长，已有多篇论文探讨了此类服务的影响。文中描述了患者与心理学家接触后的益处，但少数使用对照组的研究并未显示出长期效果。然而，评估心理治疗的整体效果存在若干方法学问题，许多研究在抽样程序和相关测量方法的使用上存在严重缺陷。由于心理治疗并非单一实体，而是包含针对不同类型问题的多种干预措施，此类研究不太可能得出明确结果。因此，需要一种更具区分性的评估方法来评估初级保健中心理治疗服务的有效性。
