Hello Zbigniew Wajda

Some papers that might help:

Corrigan, P. W., Watson, A. C., & Barr, L. (2006). The self-stigma of mental illness: Implications for self-esteem and self-efficacy. Journal of social and clinical psychology, 25(8), 875-884.

The fulltext is available from the author’s publication page on ResearchGate:

https://www.researchgate.net/publication/247839494_The_SelfStigma_of_Mental_Illness_Implications_for_SelfEsteem_and_SelfEfficacy

In study 2 of this paper, measures of self-esteem are discussed, and referenced to the paper below, which used the Rosenberg Self-esteem Scale (1965):

Torrey, W. C., Mueser, K. T., McHugo, G. H., & Drake, R. E. (2000). Self-esteem as an outcome measure in studies of vocational rehabilitation for adults with severe mental illness. Psychiatric Services, 51, 229-233.

The following paper also records the use of the Rosenberg Self-esteem Scale:

Wilfley, D. E., Welch, R. R., Stein, R. I., Spurrell, E. B., Cohen, L. R., Saelens, B. E., ... & Matt, G. E. (2002). A randomized comparison of group cognitive-behavioral therapy and group interpersonal psychotherapy for the treatment of overweight individuals with binge-eating disorder. Archives of General Psychiatry, 59(8), 713-721.

The paper below records the use of the Index of Self-Esteem (Hudson, W. W. (1982). The Clinical Measurement Package: a field manual. Homewood: Dorsey Press.).

Knight, M. T., Wykes, T., & Hayward, P. (2006). Group treatment of perceived stigma and self-esteem in schizophrenia: a waiting list trial of efficacy. Behavioural and Cognitive Psychotherapy, 34(03), 305-318.

The paper below does not relate to group psychotherapy:

Zeigler–Hill, V., & Abraham, J. (2006). Borderline personality features: Instability of self–esteem and affect. Journal of Social and Clinical Psychology, 25(6), 668-687.

Regarding the following paper - you may think that self-esteem was inferred rather than frequently mentioned per se:

Gilbert, P., & Procter, S. (2006). Compassionate mind training for people with high shame and self‐criticism: Overview and pilot study of a group therapy approach. Clinical Psychology & Psychotherapy, 13(6), 353-379.

http://www.compassionfocusedtherapy.com.au/uploads/1/0/9/5/10959753/gilbert_compassionate_mind_training.pdf

The below reference relates to Ch. 6 but the book is available on Google to sample:

 O’Brien, E. J., Bartoletti, M., & Leitzel, J. D. (2006). Self-esteem, psychopathology, and psychotherapy. Self-esteem issues and answers: A sourcebook of current perspectives, 306-315.

Hope these help

Article The Self?Stigma of Mental Illness: Implications for Self?Est...

I don't remember the articles or the authors specifically, but I am aware of the fact that high self esteem, as well as low self esteem, have a negative effect on psychological health.

I would also recommend approaching a related construct, which is more specific and may help with developing your design, namely self-efficacy (SE). Also, there many well-known and validated scales were developed for SE.

Examples of specific constructs may provide more explanatory power, such as SE in handling psychological symptoms.

You may know Irvin Yalom's classic textbook, Theory and Practice of Group Psychotherapy in which he talked about an interpersonal theory of psychopathology and an interactional model of group psychotherapy (Please see the attached link). Because he is an excellent researcher, theoretician, and practitioner, Yalom discussed the relationship between self-awareness, self-esteem/self-acceptance, and self-expansion; he provided a very good review of the research done in the eleven therapeutic factors in the first four chapters of his book.

Best,

Maye it's better to you searching to melanie fennell. She has written a book titled Overcoming low self esteem, cbt based and new approach to psychopthology and treatment on this topic.

Kristin Neff does work on self-compassion and has compared it to self-esteem. She makes the point that high self-esteem can be related to negative outcomes. The following article and more are available on her website: www.self-compassion.org.

Dear Zbigniew:

We determined that the Piers Harris Self Concept Scale scores of children with PTSD were significantly lower than the scores of traumatized youth without PTSD and controls. The Piers Harris scores Traumatized children without PTSD and non traumatized controls were not significantly different.
