Abstract BACKGROUND: Evidence‑based performance competence has a significant impact on the
performance of care measures. The higher the qualifications of nurses, the more effective and
desirable their performance. Evidence‑based practice demonstrates the competencies and abilities
of nurses. There is a need for valid and reliable tools for evaluating and promoting evidence‑based
competence in nursing students, and there are few tools in reviewing studies, but they have not
considered the cultural dimension. The purpose of this study is to validate cultural competence in
evidence‑based practice for nursing students.
MATERIALS AND METHODS: A methodological and validation study was conducted in the School
of Nursing and Midwifery of Kermanshah and Ilam University of Medical Sciences in 2018. The
Evidence‑Based Performance Competency Questionnaire (  EBP‑COQ) is one of the most valid tools
used in various studies by Ruzafa‑Martinez et al. Initially, the original version of the competence in
evidence‑based practice questionnaire was translated into Persian after securing a permission from
the designer of the tool. Totally 300 nursing students were selected through simple sampling method
and entered into the study. The validity of the tool was evaluated using face validity and performing
factor analysis. The reliability of the questionnaire was evaluated using Cronbach’s alpha and internal
consistency. Statistical works were carried out in SPSS and AMOS.
RESULTS: To determine the content validity of the tool, comparative fit index of the statements
was obtained equal to 0.88. Factor analysis of the items yielded acceptable and statistically
significant results (P < 0.001). The reliability of the tool was determined using internal consistency
method (Cronbach’s alpha) for the whole tool, which was equal to 0.7. The reliability of the
questionnaire was investigated at two stages, and pretest/posttest correlation coefficients were
obtained (P < 0.05).
CONCLUSION: The questionnaire had an acceptable validity and reliability. It can be used to
evaluate evidence‑based practice. Among advantages of the tool is that it is easy to administer in
health‑care fields.

Abstract BACKGROUND: Hemodialysis patients suffer from mental disorders such as anxiety and depression.
One of the known nonpharmacological methods to eliminate these disorders is music therapy. The
present study aimed to investigate the effect of instrumental music on state depression and anxiety
in hemodialysis patients.
MATERIALS AND METHODS: This study was a clinical trial. The population was hemodialysis
patients in Hamedan in 2017 and 50 patients were selected and randomly divided into experimental
and control groups. The duration each time of the instrumental music intervention for the experimental
group was 3 weeks, 3 times a week for 20 min. Data were measured by beck depression inventory
and SpeilBerger State–Trait Anxiety Inventory‑Y1 before the intervention and immediately after
the last intervention and analyzed using Yates correction, Chi‑square test, Mann–Whitney U‑test,
independent t‑test, and Wilcoxon test.
RESULTS: No significant difference between the intervention and control groups was observed
before the study in terms of demographic variables (P > 0.05). In the intervention group, the mean
and standard deviation of the depression score before the intervention was 8.99 ± 23.68 and after
the intervention reached 7.54 ± 14.88, which shows that the variable was significant (P = 0.001);
however, no significant difference was observed in the control group. In the intervention group, the
mean of state anxiety before the intervention was 10.05 ± 53.76 and after the intervention reached
9.76 ± 42.48, which was statistically significant (P = 0.004), while no significant difference was
observed in the control group.
CONCLUSION: The results indicate the positive effect of instrumental music on reducing anxiety
and depression in hemodialysis patients. It is recommended that this therapy be used as a nursing
method to reduce state anxiety and depression in hemodialysis patients.

Abstract BACKGROUND: Physically disabled people experience more restrictions in social activities than
healthy people, which are associated with lower level of well‑being and poor quality of life (QoL).
STUDY DESIGN: A cross‑sectional study was conducted
METHODS: This study was investigated on among 302 eligible physically disabled people. The
predictive role of the demographics and clinical characteristics, anxiety and depression, physical
activity, and self‑efficacy on the 36‑Item Short Form Health Survey (SF‑36) was examined.
STATISTICAL ANALYSIS USED: Statistical analysis used univariate and multivariate regression
models.
RESULTS: Gender, self‑reported physical activity levels, use of the disability aid tools, and depression
were significantly predictors of the physical component summary (PCS) (R2 = 0.20, P < 0.001). We
realized that anxiety, depression, and self‑efficacy could significantly predict the mental component
summary (MCS) (R2 = 0.43, P < 0.001).
CONCLUSIONS: Study results revealed that four and three variables could predict 20% and 43%
of PCS and MCS variations, respectively. These findings warranted the detection of QoL risk factors
and establishment of targeted interventions to optimize the health‑related QoL among physically
disabled people.
