ObjectiveTo develop and assess the reliability and validity of a new instrument used during the third trimester of pregnancy to measure women’s confidence in their ability to achieve physiologic birth, the Preparation for Labor and Birth (P-LAB) instrument.DesignTwo-phase instrument development study that consisted of item generation and a prospective field test.SettingField testing occurred in five midwestern U.S. prenatal clinics.ParticipantsParticipants in the field test were 203 nulliparous and parous pregnant women who intended to give birth vaginally.MethodsPsychometric testing consisted of test–retest reliability testing and assessments of content validity, face validity, and construct validity. We measured construct validity using exploratory factor analysis and correlation with the Sense of Coherence Scale.ResultsThe 22-item P-LAB showed good content validity, good internal consistency, and stability over time. All items had content validity index scores greater than or equal to 0.8, and the total instrument content validity index was 0.95. We identified four factors related to women’s confidence in their ability to achieve physiologic birth: Planned Use of Pain Medication, Relationship With Care Provider and Supportive Birth Environment, Beliefs About Labor, and Labor Support (social and professional). Cronbach’s alpha coefficient for the four extracted factors were .93, .76, .73 and .74, respectively. Intraclass correlation [95% confidence interval] for the total questionnaire was .92 [.88, .94]. We found no linear association between total P-LAB scores and sense of coherence.ConclusionOur findings demonstrate acceptable initial psychometric properties for the P-LAB instrument. Additional testing is required to evaluate the instrument’s construct, convergent, and divergent validity. 相似文献

People with asthma suffer from impaired health-related quality of life (HRQL), but the determinants of HRQL among asthmatics are not completely understood. The aim of this investigation was to study determinants of low HRQL in asthmatics and to study whether the determinants of HRQL differ between sexes and age groups. A cohort of three age groups in Sweden was investigated in 1990 using a questionnaire with focus on respiratory symptoms. To study quality of life, the generic instrument Gothenburg Quality of Life was used. The participants were also investigated with interviews, spirometry, and allergy testing. Asthma was diagnosed in 616 subjects. Fifty-eight per cent (n = 359) of the subjects were women; and 24% were smokers, 22% ex-smokers, and 54% were non-smokers. Women were more likely than men to report poor health-related quality of life. Respiratory symptoms severity was another independent determinant of a lower quality of life as well as airway responsiveness to irritants. Current and former smokers also reported lower quality of life. Finally, absenteeism from school and work was associated with lower quality of life. Factors such as sex, smoking habits, airway responsiveness to irritants, respiratory symptom severity, allergy, and absenteeism from school and work were associated with low HRQL in asthmatics. 相似文献
