ABSTRACT Self-esteem is a major concern in the treatment of patients with personality disorders in general. In patients with borderline personality disorder, low self-esteem is associated with factors contributing to suicidal and self-injurious behaviour. At the moment there are no well-proven interventions that specifically target low self-esteem. Recently, a new approach, Competitive Memory Training or COMET, aimed at the enhancement of retrieving beneficial information from memory, appeared to be successful in addressing low self-esteem in different patient populations.
To assess whether COMET for low self-esteem is also an effective intervention for patients with personality disorders.
91 patients with personality disorders who were already in therapy in a regular mental health institution were randomly assigned to either 7 group sessions of COMET in addition to their regular therapy or to 7 weeks of ongoing regular therapy. These latter patients received COMET after their “7 weeks waiting period for COMET”. All patients that completed COMET were contacted 3 months later to assess whether the effects of COMET had remained stable.
Compared to the patients who received regular therapy only, patients in the COMET + regular therapy condition improved significantly and with large effect sizes on indices of self-esteem and depression. Significant differential improvements on measures of autonomy and social optimism were also in favour of COMET, but had small to intermediate effect sizes. The therapeutic effects of COMET remained stable after 3 months on three out of the four outcome measures.
COMET for low self-esteem seems to be an efficacious trans-diagnostic approach that can rather easily be implemented in the treatment of patients with personality disorders.

    ABSTRACT: The aim of the present study was to examine the associations between self-esteem, motive satisfaction, and body weight in acute (acAN) and recovered (recAN) inpatients with anorexia nervosa (AN) and in healthy controls. Both acAN and recAN showed lower levels of self-esteem as compared with healthy controls but did not differ from each other. In acAN, decreased body weight was associated with increased self-esteem. Satisfaction of an achievement motive but not satisfaction of a superiority motive mediated this association. No such correlations could be observed in the other groups. This is the first study to show an often assumed association between decreased body weight and increased self-esteem in AN patients. These preliminary results strengthen the assumption that low body weight may foster self-esteem in patients with acAN, mainly through the satisfaction of an achievement motive. Copyright © 2012 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Self-esteem should be focused very early in the treatment of AN since weight gain may deprive the patient of an important source of self-esteem. Treatment interventions should be attuned to underlying motives of threatened self-esteem; in AN patients, the enhancement of self-esteem via weight loss seems to be rather fuelled by the satisfaction of an achievement motive than by the satisfaction of a superiority motive. Specific trainings to improve self-esteem in AN patients seem to be promising as an add-on to regular treatment.

    ABSTRACT: This study investigates whether depression can be ameliorated by weakening the associations between auditory verbal hallucinations and easily activated networks with negative self-evaluations, by strengthening the access to competing memories of positive self-esteem. Design.  A randomized controlled clinical trial comparing competitive memory training (COMET) with treatment as usual (TAU) in schizophrenia patients with persistent auditory hallucinations. Patients with schizophrenia-spectrum disorders were randomized into COMET (n = 39) versus TAU (n = 38). COMET consisted of seven sessions with four stages: (1) identification of aspects of negative self-esteem reinforced by the voice; (2) retrieval and re-living of memories associated with positive self-esteem; (3) positive self-esteem is brought in to compete with the content of the voices to weaken the association between voice content and negative self-evaluation; and (4) learning to disengage from the voices and to accept the voices as psychic phenomena. Compared to TAU the COMET group improved on depression but there were no significant effects on auditory hallucinations. The effect of COMET on depression was fully mediated by self-esteem and acceptance of voices, and partially mediated by social rank and attributed power to the voices. COMET can be helpful in reappraising the meaning and changing the emotional impact of auditory hallucinations. These findings are consistent with the results of comparable COMET protocols applied in other psychiatric diagnoses. The technique can be used within regular cognitive behavioural therapy.

    ABSTRACT: A deficit in the ability to experience pleasure (anhedonia) is one of the core symptoms of depression. However, therapy to date has predominantly focused on understanding elevations in negative emotion experience in depression and relatively neglected ways to reconnect individuals to positive experience. This article reviews current insights into blunted positivity in depression, evaluating evidence that depression leads to disturbances in anticipation (positive emotion experience when approaching a goal or a rewarding stimulus) and consummation (positive emotion experience when attaining a goal or rewarding stimulus), as well as impaired positive emotion recognition. The case is made that existing treatments are only partially effective and that therapy outcomes are likely to be improved by focusing on augmenting positivity, capitalizing on emerging insights from positive affective neuroscience. Existing and emerging therapeutic techniques that may aid the promotion of positivity are critiqued, and some suggestions for future research and clinical practice are outlined.
