Institutionalized retarded children were randomly assigned to 11 sessions of directive play therapy (N = 5), nondirective play therapy (N = 5), or no treatment (N = 4). Student nurses were therapists. The Denver Developmental Screening Test was administered before and after treatment. For the Fine Motor and Personal-Social scales, a significant interaction effect (p smaller than .05) was found between treatment group and measurement period (pre vs. post). The interactions tended to support the hypothesis that play therapy was effective in increasing developmental level but not the hypothesis that directive therapy was more effective than nondirective therapy.
将福利院中的智障儿童随机分为三组，分别接受11次指导性游戏治疗（N = 5）、非指导性游戏治疗（N = 5）或不接受治疗（N = 4）。治疗师由实习护士担任。在治疗前后分别进行丹佛发育筛查测试。对于精细动作和个人社交能力量表，发现治疗组与测量时间（治疗前与治疗后）之间存在显著的交互作用（p小于0.05）。这些交互作用倾向于支持游戏治疗能有效提高发育水平这一假设，但不支持指导性治疗比非指导性治疗更有效的假设。
