The scale is a shorter version of the SCL-90 , a self-report inventory consist of 90 items that measure psychosomatic and psychological symptoms for the recent week. The shorter version includes 10 items and has been used in several studies for global psychological distress. Participants are asked to rate each item on a 5-point Likert scale (0 = "no at all" to 4 = "extremely") (e.g. feeling blue). Higher score represents more psychopathology. Cronbach's alpha of the scale was 0.87. In the current study we will translate the questionnaire to Hebrew using back-translation.

The EAPPS is a scale designed to assess expectations about the active processes assumed to facilitates change in psychotherapy. It includes 32 items representing 7 factors: establishment of positive therapist-client relations, verbal processing of therapist-client relations, exploration of unexpressed contents, the ability to share sensitive contents openly and secretly, working through specific emotional problems, therapy fosters resilience and therapy provides tools for cognitive control. Each respondent will be asked to rate their level of agreement with each item as a mechanism therapy work through on a 7-point Likert scale ranging from 1 (Not at all) to 7 (To a large extent). The score for each factor is calculated by the sum of its items. The EAPPS have been developed in Hebrew and translated into English. Cronbach's alpha of the subscales ranged between .66-.85, and internal and external validity has been established.

for measuring outcome expectations we will use this 6 items scale divided to two parts. The first one addresses what the subject thinks and includes three credibility items rated on a 9-point Likert-type scale. the minimum value is 1 (not at all sure/think the therapy will be useful) and the maximum value is 9 (very useful). Also, one outcome expectancy item rated from 0 to 100% in 10 jumps (e.g. 0, 10%, 20%...).''By the end of the therapy period, how much improvement in your presenting concerns/problems do you think will occur?''. The second part includes two items rated on a 9-point Likert-type scale that addresses to what the subject feels (e.g." By the end of the therapy period, how much improvement in your presenting concerns/problems do you feel will occur?'. For reliability measure, the total scale standardized alpha was r=0.85. This measure was used in several studies for outcome expectations and was correlated with other outcome expectations measures.

The MULTI is a 30 items questionnaire focused on interventions from eight different psychotherapy orientations (behavioral, cognitive, dialectical behavioral, interpersonal, person centered, psychodynamic, process- experiential, and common factors). Items are rated from 1(not typical at all) to 5 (extremely typical).
