Construct validity and factor structure of the Pittsburgh Sleep Quality Index among pregnant women in a Pacific-Northwest cohort

Sleep disorders continue to rise and have been estimated to affect around half of the global population. Poor sleep quality and insomnia are also linked to various health issues in different populations. The Pittsburgh Sleep Quality Index (PSQI) is one of the most commonly used tool to assess sleep quality. It has been tested in various clinical and non-clinical settings and populations but mostly in developed world. Literature is limited from Arab region and further scarcity of studies is observed among health providers from the region. This study aimed to assess the construct validity and factor structure of PSQI among physicians in Jeddah, Kingdom of Saudi Arabia. This cross-sectional study used the PSQI tool with 19 items and 7 components on 330 physicians working in Jeddah. Data was entered and analyzed in IBM SPSS and AMOS version 22. Cronbach alpha was 0.745. Construct validity showed satisfactory results. Exploration of factor structure with Confirmatory factor analysis (CFA) showed 1-factor model as better fit. Among three models, 3-factor model showed least fit indices. The study findings showed some similarities as well as differences to comparable studies using PSQI in other settings that requires further as well as continuous exploration of the dynamic issue in similar and diverse settings.

Lebih dari separuh wanita hamil yang merasa tidak nyaman karena mual dan muntah dilaporkan telah mengalami gangguan tidur selama kehamilan. Durasi tidur yang tidak memadai dan kualitas tidur yang buruk selama kehamilan dapat meningkatkan kehamilan dengan risiko, termasuk gangguan pertumbuhan janin, dan depresi pascapersalinan. Yoga umumnya digunakan untuk relaksasi dan terbukti efektif untuk mengurangi stres dan kecemasan pada wanita hamil sehingga dimungkinkan untuk meningkatkan kualitas tidur bagi wanita hamil. Salah satu bentuk latihan yoga pada ibu hamil adalah pranayama dan postur yoga restoratif. Tujuan dari penelitian ini adalah untuk mengetahui apakah pranayama dan postur yoga restoratif efektif untuk meningkatkan kualitas tidur pada wanita hamil. Studi quasy eksperimental dengan kelompok kontrol ini dilakukan pada 58 wanita hamil dengan mual muntah yang didapatkan dengan metode purposive sampling. Responden dibagi menjadi dua kelompok, 29 responden di setiap kelompok. Pranayama dan postur yoga restoratif diberikan pada kelompok intervensi dalam 30 menit selama 7 hari terus menerus. Kualitas tidur diukur oleh Pittsburgh Sleep Quality Index (PSQI). Hasil analisis data menggunakan uji Chi-Square menunjukkan bahwa tidak ada perbedaan dalam skor kualitas tidur ibu hamil sebelum dan sesudah diberi pranayama dan postur yoga restoratif (p>0.05). Wanita hamil trimester kedua dan ketiga yang mengalami mual dan muntah dalam penelitian ini tampaknya tidak mengalami peningkatan kualitas tidur setelah melakukan pranayama dan postur yoga restoratif. Frekuensi dan keteraturan dalam melakukan yoga menjadi poin penting yang perlu diperhatikan untuk hasil yang lebih ba

ABSTRACT Background: During pregnancy, pregnant women will experience a variety of changes in reproduction that are physiological and sometimes pathological. Sleep difficulties are generally more common in early pregnancy. Then this sleepless complaint will reappear at the end of pregnancy. Persistent sleep disorders will interfere with the physical and psychological pregnant women. Purpose of this study is to know the effect of back massage on sleep quality of trimester III pregnant women Methods: Research type experimental research, design pre experiment designs with one group pretest posttest design. Population in this research is trimester mother III at BPM Tiara Iswantika Wonosari District of Pekalongan Regency of East Lampung year 2018, sample taken counted 29 people with purposive sampling technique. Analysis in this research use paired sample t test.Results of statistical tests showed that the mean maternal sleep quality score on the measurement result using the Pittsburgh Sleep Quality Index (PSQI) questionnaire before (pretest) the back massage intervention was 6,28±1,461 and after (posttest) the back massage intervention was 5, 03±1,349 with an mean difference of 1,241±0,739. In result of paired sample t test showed back massage proved to have an effect on to sleep quality of pregnant woman trimester III (p-value 0,000 <a0,05). Conclusion: With the results of this study is expected pregnant women can do back massage therapy to reduce tension, relax the body and improve sleep quality.Suggestion Currently there is still no counseling related to back massage, so health workers should be able to provide back massage counseling to pregnant women because back massage has become part of supporting therapy in the health sector to improve health status, especially in improving the quality of sleep for pregnant women. Keywords : Sleep quality, back massage ABSTRAK Latar Belakang: Pada masa kehamilan, ibu hamil akan mengalami berbagai perubahan pada sistrem reproduksi yang bersifat fisiologis dan terkadang bersifat patologis. Kesulitan tidur umumnya lebih banyak dialami pada awal kehamilan. Kemudian keluhan sulit tidur ini akan kembali muncul pada akhir kehamilan. Gangguan tidur yang terus menerus akan mengganggu fisik dan kejiwaan ibu hamil.Tujuan: diketahuinya pengaruh back massage terhadap kualitas tidur ibu hamil trimester III Metodologi: Jenis penelitian experimental research, desain pre experiment designs dengan rancangan one group pretest posttest. Populasi dalam penelitian ini adalah ibu trimester III di BPM Tiara Iswantika Wonosari Kec. Pekalongan Kab. Lampung Timur tahun 2018, sampel yang diambil sebanyak 29 orang dengan teknik purposive sampling. Analisis dalam penelitian ini menggunakan uji paired sample t test.Hasil: uji statistik menunjukkan bahwa Rata-rata skor kualitas tidur ibu hamil pada hasil pengukuran menggunakan kuesioner the Pittsburgh Sleep Quality Index (PSQI) sebelum (pretest) intervensi back massage adalah 6,28±1,461 dan setelah (posttest) intervensi back massage adalah 5,03±1,349 dengan selisih rata-rata 1,241±0,739. Pada hasil uji paired sample t test menunjukkan back massage terbukti berpengaruh terhadap kualitas tidur ibu hamil trimester III (p-value 0,000<a0,05). Kesimpulan: Dengan hasil penelitian ini diharapkan ibu hamil dapat melakukan terapi back massage untuk menurunkan ketegangan, merileksasi tubuh dan meningkatkan kualitas tidur.Saran Saat ini masih belum ada penyuluhan terkait back massage maka hendaknya bagi tenaga kesehatan dapat memberikan penyuluhan back massage kepada ibu hamil karena back massage telah menjadi bagian dari terapi penunjang dalam bidang kesehatan untuk meningkatkan derajat kesehatan terutama dalam meningkatkan kualitas tidur ibu hamil. Kata Kunci : Kualitas tidur, back massage

The Pittsburgh Sleep Quality Index (PSQI) is a widely used measure for assessing sleep impairment. Although it was developed as a unidimensional instrument, there is much debate that it contains multidimensional latent constructs. This study aims to investigate the dimensionality of the underlying factor structure of the PSQI in a multi-ethnic working population in Singapore. The PSQI was administered on three occasions (baseline, 3 months and 12 months) to full-time employees participating in a workplace cohort study. Exploratory factor analysis (EFA) investigated the latent factor structure of the scale at each timepoint. Confirmatory factor analysis (CFA) evaluated the model identified by EFA, and additionally evaluated it against a single factor and a three-factor model. The EFA identified a two-factor model with similar internal consistency and goodness-of-fit across each timepoint. In the CFA, the two- and three-factor models were both superior to the unidimensional model. The two- and three-factor models of the PSQI were reliable, consistent and provided similar goodness-of-fit over time, and both models were superior to the unidimensional measure. We recommend using the two-factor model to assess sleep characteristics in working populations in Singapore, given that it performs as well as the three-factor model and is simpler compared to the latter.
