When faced with a personal problem people typically give better advice to others than to themselves. A previous study showed how it is possible to enact internal dialogue in virtual reality (VR) through participants alternately occupying two different virtual bodies – one representing themselves and the other Sigmund Freud. They could maintain a self-conversation by explaining their problem to the virtual Freud and then from the embodied perspective of Freud see and hear the explanation by their virtual doppelganger, and then give some advice. Alternating between the two bodies they could maintain a self-dialogue, as if between two different people. Here we show that the process of alternating between their own and the Freud body is important for successful psychological outcomes. An experiment was carried out with 58 people, 29 in the body swapping Self-Conversation condition and 29 in a condition where they only spoke to a Scripted Freud character. The results showed that the Self-Conversation method results in a greater perception of change and help compared to the Scripted. We compare this method with the distancing paradigm where participants imagine resolving a problem from a first or third person perspective. We consider the method as a possible strategy for self-counselling.

In this article we present a system of 45 content categories for analyzing personal constructs elicited in the context of a repertory grid administration. These categories are divided into six basic areas: moral, emotional, relational, personal, intellectual/operational, and values/interests, as well as two possible supplemental areas: existential and concrete descriptors. We study the reliability of this classification system using a sample of 843 constructs extracted from the grids of 57 subjects and coded by two independent judges. The degree of consensus achieved is very satisfactory.

Alejandro Ávila-EspadaThe idea that internal conflicts play a significant role in mental health has been extensively addressed in various psychological traditions, including personal construct theory. In the context of the latter, several measures of conflict have been operationalized using the Repertory Grid Technique (RGT). All of them capture the notion that change, although desirable from the viewpoint of a given set of constructs, becomes undesirable from the perspective of other constructs. The goal of this study is to explore the presence of cognitive conflicts in a clinical sample (n = 284) and compare it to a control sample (n = 322). It is also meant to clarify which among the different types of conflict studied provides a greater clinical value and to investigate its relationship to symptom severity (SCL-90-R). Of the types of cognitive conflict studied, implicative dilemmas were the only ones to discriminate between clinical and nonclinical samples. These dilemmas were found in 34% of the nonclinical sample and in 53% of the clinical sample. Participants with implicative dilemmas showed higher symptom severity, and those from the clinical sample displayed a higher frequency of dilemmas than those from the nonclinical sample.

Objective: The objective of this paper is to assess the reliability and validity of the Spanish translation of the Clinical Outcomes in Routine Evaluation – Outcome Measure, a 34-item self-report questionnaire that measures the client’s status in the domains of Subjective well-being, Problems/Symptoms, Life functioning, and Risk. Method: Six hundred and forty-four adult participants were included in two samples: the clinical sample (n=192) from different mental health and primary care centers; and the nonclinical sample (n=452), which included a student and a community sample. Results: The questionnaire showed good acceptability and internal consistency, appropriate test–retest reliability, and acceptable convergent validity. Strong differentiation between clinical and nonclinical samples was found. As expected, the Risk domain had different characteristics than other domains, but all findings were comparable with the UK referential data. Cutoff scores were calculated for clinical significant change assessment. Conclusion: The Spanish version of the Clinical Outcomes in Routine Evaluation – Outcome Measure showed acceptable psychometric properties, providing support for using the questionnaire for monitoring the progress of Spanish-speaking psychotherapy clients.

Although the use of repertory grids in psychological research has proliferated, studies of their psychometric properties are relatively rare. For this reason, we studied the reliability and convergence of several measures of cognitive structure derived from grids, including intensity, percentage of variance accounted for by the first component, cognitive complexity, ordination, extremity of ratings, self-ideal discrepancy, and self-other discrepancy, as well two measures of rating stability, construct consistency and factor loading consistency. Eighty-two Spanish (Catalan) and American participants completed small and large grids on each of four occasions, which enabled exploratory analyses of the impact of grid size and subject characteristics on the structural scores obtained. Results indicated that the majority of scores showed impressive test-relest reliability (modal r = .85 for periods up to 1 month), but also suggested a gradual tightening effect across subsequent administrations. In general, scores intercorrelated in theoretically anticipated ways, converging on the assessment of cognitive differentiation and discrimination of elements within construct dimensions. The results have implications for the reactivity of structural scores to variations in grid format, as well as for use of grids in the study of sex differences and cross-cultural comparisons.
About Me
Guillem Feixas graduated from the Universitat de Barcelona (UB), Barcelona, Spain in 1984 and obtained a scholarship from the Ministry of Education and Science to complete his doctorate. During this period, he completed his clinical training in existential psychotherapy and systemic family therapy (Hospital de la Santa Creu i Sant Pau). In 1987, he was awarded the Young Investigator Award by the Institute for Personal Construct Psychology. In the 1988–1989 academic year, he held a postdoctoral position at Memphis State University (now the University of Memphis). With another ministerial scholarship, he returned to UB to work in the Department of Personality, Assessment, and Psychological Treatments (currently merged into the Clinical Psychology and Psychobiology Department) where he obtained the position of associate professor (tenure) in 1992 and became a full professor in 2011. Since then, he has taught undergraduate courses on psychotherapy, clinical psychology, and systemic family intervention and has taught in a variety of master’s programs in the Faculty of Psychology at UB. The primary focus of his research has been to advance the understanding of interpersonal construing and to further the knowledge of its role in health (both mental and physical) and in the process of psychotherapy. To this aim, personal construct and self-regulation theories have been important sources of inspiration for implementation, both in research and clinical practice.
