This study aimed to develop and validate a Polish version of the Personal Growth Initiative Scale-II (PGIS-II; Robitschek et al.

<b>Background</b><br /> This study presents the Polish validation of the Brief Illness Perception Questionnaire, a nine-item scale which was constructed to assess the cognitive and emotional representations of illness among Polish patients. This tool is derived from the Common-Sense Model of Self-Regulation of Health and Illness.<br /> <br /> <b>Participants and procedure</b><br /> This study included 923 chronically ill people with the following diseases: eczema (E), bronchial asthma (BA), chronic obstructive pulmonary disease (COPD), rheumatoid arthritis (RA), Hashimoto’s disease (HD), diabetes type II (D), acne (A), glaucoma and cataract (G, C), HIV/AIDS, ischaemic heart disease (IHD), psoriasis (P), breast and stomach cancer (C), and multiple sclerosis (MS). Test–retest reliability was assessed in 358 patients with selected chronic illnesses. Concurrent validity was assessed by correlating Kurtzke’s EDSS and the Brief IPQ in 140 MS patients. Discriminant validity was verified by comparing means for the tool among four groups of patients.<br /> <br /> <b>Results</b><br /> The Polish version of the Brief IPQ showed good test–retest reliability. The scale also demonstrates good concurrent validity in MS patients. The discriminant validity of the Brief IPQ was supported by its ability to distinguish among different illnesses.<br /> <br /> <b>Conclusions</b><br /> The Brief IPQ is a good, short and easy to use tool for assessing the perceptions of illness among Polish patients.

The aim of this paper is to present the results of Polish validation of Transgression -Related Interpersonal Motivations questionnaire (TRIM-18) by McCullough, Root, and Cohen (2006) which measures the phenomena of forgiveness. The article contains a description of the procedure of Polish translation, the results of the test reliability, discriminant and confirmatory validity. The study was conducted among 530 participants aged between 18 and 84 (345 females and 185 males). Eleven questionnaires were used for assessing the validity of the measurement. This study confirms that the structure of Polish TRIM-18 is relevant to the English language version. Polish TRIM-18 is also a very reliable tool. It can be successfully used in Polish conditions.
