Purpose: This paper follows a two-fold objective: First it examines the relationship between the external factors of compensation, support, empowerment, boundaries and expectations, pre-service and in- service training and Iranian EFL teachers’ performance. Second, it searches for the moderating effect of self-regulation on the relationship between teachers’ external assets and their performance. Methodology: To achieve the above aims, a quantitative approach to research was employed. The samples included two hundred Iranian EFL teachers of universities and English institutes of Kerman, Iran. The data were collected by means of self-administered questionnaires and analyzed by AMOS software. The direct structural model was employed to determine the path relationships between the external factors and teachers’ performance. Findings: The result showed that external assets had a positive and significant effect on the Iranian EFL teachers' performance as dependent variable (β = .372, C. R= 6.211, P <.05). Moreover, self-regulation moderates the path relation between two of the variables: boundaries and expectation and the EFL teachers' performance. The path relation between the other four variables of the external assets including pre-service and in- service training, support, compensation and empowerment for low and high self-regulation was not found to be significant, i.e. self-regulation moderation effect for these relations was not supported. Discussion: Working conditions for teachers should be best promote effective learning and enable teachers to concentrate on their professional tasks.

The purpose of this study was to determine the efficacy of acceptance-based treatment and commitment to interdependence, loneliness and Attributional styles of addicts' wives. The present study was a quasi-experimental design with a pretest-posttest with control group and from the perspective of the purpose, the research was applied. The statistical population of the study consisted of all wives of drug addicts in Tehran. The sample of the present study was based on objective sampling based on available sampling including 30 subjects (15 subjects in each group, 15 in the experimental group and 15 in the control group). The research instruments were Spen-Fisher questionnaire (1991), loneliness questionnaire, Attributional style styles, and adherence-based therapy package. Data were analyzed by repeated measures of covariance and Bonferrini test. Findings showed that considering the fact that the level of significance is smaller than α, also considering that the effect of pre-test was covariate by covariance test, it can be concluded that in the context of the variables of dependency, loneliness and Attributional styles, Treatment based on admission and commitment has been significantly effective. Also, considering all the three variables, we can conclude that the experimental intervention has led to changes in the experimental group. So the treatment affected the decrease in dependency and loneliness and the change in the Attributional style.
