BACKGROUND The only existing NVP-specific quality of life (QOL) questionnaire is the "Health-Related Quality of Life for Nausea and Vomiting during Pregnancy" (NVPQOL). However, the reliability and validity of the NVPQOL have never been established. In order to justify its usage, the internal consistency and criterion validity of the NVPQOL questionnaire must be ascertained. METHODS A prospec...

this research was conducted with the purpose of analyzing improvement mechanisms of human resource development (hrd) in agriculture faculties. this survey research was descriptive-explanatory. the population of this research consisted of all agricultural faculty members of iran universities (n=1178). data was collected using multi-stage random sampling method. finally, 248 questionnaires were c...

let $r$ be a reversible ring which is $alpha$-compatible for an endomorphism $alpha$ of $r$ and $f(x)=a_0+a_1x+cdots+a_nx^n$ be a nonzero skew polynomial in $r[x;alpha]$. it is proved that if there exists a nonzero skew polynomial $g(x)=b_0+b_1x+cdots+b_mx^m$ in $r[x;alpha]$ such that $g(x)f(x)=c$ is a constant in $r$, then $b_0a_0=c$ and there exist nonzero elements $a$ and $r$ in $r$ such tha...

Adverse events are common in acute clinical settings but little is known about these events occurring after Intensive Care discharge. This study aimed to develop a reliable and valid tool for exploring clinicians' opinions of factors associated with post-Intensive Care adverse events. A convenience sample of Australian Intensive Care Liaison Nurses was invited to complete and appraise a questio...

The aim of the study was to examine the reliability and validity of the Turkish version of the Hamilton Depression Rating Scale (HDRS). Ninety-four patients with major depression/depressive mood disorders and 40 healthy controls participated in the study. The severity of depression was assessed with the HDRS, Beck Depression Inventory (BDI), and Clinical Global Impression score (CGI). The test-...

OBJECTIVE The current study aimed to validate the construct and reliability of an emotional intelligence scale. METHOD The Trait Meta-Mood Scale-24 was applied to 349 nursing students. The process included content validation, which involved expert reviews, pilot testing, measurements of reliability using Cronbach's alpha, and factor analysis to corroborate the validity of the theoretical mode...

The purpose of this study was to examine the psychometric properties of the Autism Program Environment Rating Scale (APERS), an instrument designed to assess quality of program environments for students with autism spectrum disorder. Data sets from two samples of public school programs that provided services to children and youth with autism spectrum disorder were utilized. Cronbach alpha analy...

Typically, when using existing scales, researchers conduct a confirmatory factor analysis and estimate reliability indices such as Cronbach alpha. Results are then used to select items that are subsequently incorporated in models. However, this process is inefficient as results from several studies consistently indicate that certain factors have low factor loadings. This study addressed this is...
