Abstract
Background & objectives: Content validity is the first type of validity that has to be ensured during the design of a tool. Its prerequisite for other validities and its close relationship with the tool reliability place it in a vital position in the questionnaire design. However, since it has not been paid enough attention in national publications therefore in this paper we will explain the different steps in preparing an appropriate content for questionnaires and also their assessment.
Methods: The steps of the content validation process for designing valid and reliable questionnaires have been explained in this paper: development (domain identification, items generation and instrument construction), Judgment – quantification (determining the inter rater agreement among experts, determining the clarity and relevancy of each of the questions along with the clarity, relevancy and comprehensiveness of the tool as a whole) have been explained.
Conclusions: The benefits of performing the content validation in questionnaire development are not increasing the possibility of accessing desirable content validity indexes (relevancy, clarity, and comprehensiveness) only, but also improving the Reliability indexes of tool and decreasing need for resources (financial and temporal) are the other benefits of this approach. Although subjective nature of experts’ responses is the problematic issue in this process but the more quantitative steps of the content validation has reduced considerable part of previous worries about this process. These issues explain why content validation has become a suitable process for questionnaire

Abstract
Background & Objectives: Although it is important to study the association between caregiver burden and individual with dementia, a little has been paid attention to this issue in Iranian population therefore the aim of study was to investigate the frequency of psychiatric symptoms and patients with dementia and caregiver burden associated with individual with dementia.
Methods: In this study 84 patients who had referred to Iran Alzheimer’s Association, along with their caregivers were included in our study. Iranian Version of Caregiver Burden and NPI questionnaires were employed. Factors affecting factors on burden was analyzed by multivariate linear regression.
Results: Our findings showed that there was at least one psychiatric disorder in all patients. Among all psychiatric symptoms delusion and elation had the highest and lowest rates with 39.3 and 2.4 percentages, respectively. Linear regression indicated that “indifference” and “irritability” symptoms were the effective psychiatric symptoms on the amount of burden placed on the caregivers.
Conclusion: The symptom frequency of irritability and other symptoms showed a statistically significant positive correlation with caregiver's NPI-D score. These findings suggest that improvement of treatments for delusions, irritability among dementia patients may reduce caregiver burden.

Abstract
Background and Objectives: Using a random sample of women aged 15 to 50 years in Tehran, this study sought to estimate the lifetime prevalence of abortion (intentional and unintentional) and to identify its associated factors.
Materials and Methods: The control data of a population-based case-control study conducted in 2014 in Tehran was used in the present study. Data from 544 randomly selected women aged 15-50 living in municipality areas of Tehran were included in this study. A multiple logistic regression model was used to investigate factors associated with abortion and to estimate the adjusted odds ratios (ORs) and 95% confidence intervals.
Results: Overall, 102 women (18.8%, 95% CI (22.4% -15.8%)) reported a lifetime history of abortion. In the logistics regression model, being single (OR =3.46, 95% CI: 1.42-8.47) older age (OR = 1.07, 95% CI: 1.04-1.11) increased the odds of a positive lifetime history of abortion. However, having a child (OR = 0.27, 95% CI: 0.11-0.65)), more education years (OR = 0.89, 95% CI: 0.82-0.96)) and higher religious beliefs (OR = 0.65, 95% CI: (0.45-0.93)) decreased the odds of a positive lifetime history of abortion..
Conclusion: High reported lifetime prevalence of abortion in the present study and its subsequent risks to maternal health highlight the need for educational interventional programs taking into account the level of education and knowledge of mothers along with their religious.
