Development and validation of the Gestalt Therapy Fidelity Scale

Common mental disorders in Gestalt therapy treatment: a multiple case study comparing patients with moderate and low integrated personality structures

Introduction

Empowerment is central to self-development and growth in Gestalt therapy. The self evolves through interactions with others, forming self- and object-relations, and ego-functions. Underlying structural functions build the ability to regulate, differentiate, and integrate experiences, leading to self-, and emotion-regulation. Our study examined the self-development of seven clients with prevalent mental health issues and structural challenges, all of whom underwent 30 sessions of Gestalt therapy in a real-world individual therapy context.

Methods

Using a multiple case study approach, we contrasted two client groups: those with moderately integrated and those with low-integrated personality structures, as defined by the operationalised psychodynamic diagnostic manual. Our exploration centered on specific factors of empowerment, therapy processes, and interventions. The study's mixed-method design encompassed quantitative outcome measures (empowerment, wellbeing, psychosocial health, and severity of personality functioning), therapy diaries from both clients and therapists, and semi-structured client interviews about empowering factors in therapy.

Results

Both groups showed positive therapy outcomes on wellbeing, psychosocial health, and empowerment. Specific empowerment-related factors included promoting experiences, relationships, and self-efficacy in the low-integrated group. Support of self-regulation was reported to be essential for successful outcomes in the moderately integrated group. While the therapy processes proceeded similarly in both groups, we observed a strong focus on body awareness-oriented interventions and promotion of verbalisation in the low-integrated group and a relationship-oriented emphasis in the moderately integrated group. Emotional experience linked to positive experience was limited in the low-integrated group, suggesting an impairment of emotional processing, including bodily felt feelings. No change was reported in the level of personality functioning after 30 sessions in both groups.

Discussion

These results underscore the need for tailored therapeutic approaches based on the client's level of personality integration. Future research should probe the long-term effects of therapy and delve deeper into shifts in personality functioning, especially concerning emotional and bodily experiences. In practical terms, therapists should prioritize linking bodily sensations with emotions for clients with low-integrated personalities. For those with moderate integration, the emphasis should be on fostering exploration, awareness, and bolstering self-regulation.

A Single-Case Design Investigation for Measuring the Efficacy of Gestalt Therapy to Treat Depression in Older Adults with Dementia in Italy and in Mexico: A Research Protocol

Psychotherapy is one of the evidence-based clinical interventions for the treatment of depression in older adults with dementia. Randomised controlled trials are often the first methodological choice to gain evidence, yet they are not applicable to a wide range of humanistic psychotherapies. Amongst all, the efficacy of the Gestalt therapy (GT) is under-investigated. The purpose of this paper is to present a research protocol, aiming to assess the effects of a GT-based intervention on people with dementia (PWD) and indirect influence on their family carers. The study implements the single-case experimental design with time series analysis that will be carried out in Italy and Mexico. Six people in each country, who received a diagnosis of dementia and present depressive symptoms, will be recruited. Eight or more GT sessions will be provided, whose fidelity will be assessed by the GT fidelity scale. Quantitative outcome measures are foreseen for monitoring participants' depression, anxiety, quality of life, loneliness, carers' burden, and the caregiving dyad mutuality at baseline and follow-up. The advantages and limitations of the research design are considered. If GT will effectively result in the treatment of depression in PWD, it could enrich the range of evidence-based interventions provided by healthcare services.
