Holt's Rorschach Measure of Adaptive Regression,Mathematical Artifact,and Prediction of Psychotherapy Outcome

In Holt's primary process system for scoring the Rorschach, a summary score of adaptive regression is derived by combining the “Defense Demand” (DD) and “Defense Effectiveness” (DE) scores associated with most responses. The adaptive regression score is criticized because its computation involves a mathematical artifact which in effect creates a score that is very similar to the simpler DE measure. An alternative method for considering DD and DE jointly as a measure of adaptive regression is presented, and this alternative method is illustrated with data from a recent psychotherapy study.     

Rorschach changes in long-term and short-term psychotherapy

Over a period of several years, repeat Korschach testing was done with two groups of patients receiving outpatient psychotherapy, a long-term group (n = 88) engaged in intensive, dynamically oriented psychotherapy and a short-term group (n = 88) involved in behavioral or gestalt therapy. Rorschach protocols were obtained at the beginning of the treatment and on three subsequent occasions, 1 year, 2 1/2 years, and 4 years later, when most of the long-term and all of the short-term patients had completed their therapy. The findings demonstrate generally beneficial effects of psychotherapy, greater change in long-term than in short-term therapy, and the validity of the Rorschach for measuring these effects and changes.     

The Rorschach Ego Impairment Index: prediction of treatment outcome in a child psychiatric population

In this study, we investigated the treatment utility of the revision of Perry and Viglione's (1991) Rorschach Ego Impairment Index (EII-2) in a sample of 53 child psychiatric inpatients. Parent ratings of symptomatic functioning on the Devereux Scales of Mental Disorders (DSMD; Naglieri, LeBuffe, & Pfeiffer, 1994) were obtained at admission, 30 days postdischarge, and 120 days postdischarge. EII-2 scores correlated with initial symptom elevations on the Critical Pathology at admission. EII-2 scores did not predict short-term response to treatment. However, EII-2 scores demonstrated moderate correlations with long-term outcome and relapse. EII-2 was related to prediction of worsening of symptoms between 30-day and 120-day follow-up as measured by Reliable Change Index scores that were computed for the Externalizing, Internalizing, Critical Pathology, and Total DSMD scales.     

Rorschach assessment of changes following psychotherapy: a meta-analytic review

I examined Rorschach assessment of personality changes following psychotherapy. I conducted a comprehensive literature search to find all studies using the Rorschach method at least twice for the same participant in connection with psychotherapy. I conducted meta-analyses for 38 samples, and I performed regression analyses to identify moderating factors. Across all Rorschach scores, the total weighted sample effect size was r = .26, and nearly half the variables obtained effect sizes higher than .30. Several moderating factors were found. Most important, effect sizes increased with longer and more intensive therapy. More concern for interscorer reliability was associated with larger effect sizes, whereas a higher degree of scorer blinding was associated with smaller effect size magnitudes. Predicted levels of change based on the regression models indicated substantial increases in effect size with longer therapies. The data indicate that many elements in the Rorschach are valid indicators of change despite the poor reputation the method has acquired within psychotherapy research.     

Leadership behavior,group climate and outcome in group psychotherapy: A study of outpatient psychotherapy groups

A recent clinical study of outpatient psychotherapy groups in a community mental health center explored the linkage between group leadership variables, group climate, and outcome. The study involved nine outpatient therapy groups, over 50 group clients, and several group therapists. A repeated measures design involving assessment of clients' outcome and level of functioning, group leadership style, and group climate was used to assess changes over a 6-month period. The findings suggest: 1) a reduction in symptoms and improved functioning for clients; 2) a similarity of perceptions by members and leaders of perceived leadership behaviors and group climate; 3) the presence of direct and indirect influences of group climate and leadership behavior on clients' outcome; and 4) a linkage between leadership behavior and group climate with the theoretical orientation of the group. The findings of the research are discussed in relation to the understanding of specific effects in group psychotherapy and the implications for construction of group psychotherapy theory.The authors would like to thank Robert Dies, Ph.D., for his helpful suggestions in the early phase of this study; Roy MacKenzie, M.D., for permission to use the Group Climate Questionnaire; Diane DePalma, Ph.D., for permission to use the Global Leadership Behavior Index; Chris Boltwood, B.A., for her untiring efforts in administering the instruments and coding and entering the data; and most importantly, the psychotherapy group members and the group therapists for their cooperation in this endeavor—without their help, this clinical study would not have been possible.A version of this paper was presented at the Annual Meeting of the American Group Psychotherapy Association, 1987, New Orleans, Louisiana.

Imagination inflation: a statistical artifact of regression toward the mean

In the imagination inflation procedure of Garry, Manning, Loftus, and Sherman (1996), subjects rated a list of events in terms of how likely each was to have occurred in their childhood. Two weeks later, some of the events were imagined; control events were not. The subjects then rated the likelihood of occurrence for each event a second time. Garry et al. (1996) reported that the act of imagining the target events led to increased ratings of likelihood. This finding has been interpreted as indicating that false events can be suggestively planted in memory by simply having people imagine them. The present study tests and confirms the hypothesis that the results that have been attributed to imagination inflation are simply a statistical artifact of regression toward the mean. The experiment of Garry et al. (1996) was reproduced (with some procedural changes), using younger and older adults. The results of Garry et al. (1996) were replicated; likelihood ratings for events initially rated low in likelihood did increase from Time 1 to Time 2. However, ratings for events initially rated high in likelihood decreased under the same conditions, and these results were consistent with the imagined target events, the target events not imagined, and the nontarget events.
