Pengaruh Sibling Relationship Terhadap Kesejahteraan Psikologis Peserta Didik SMA Negeri dJakarta Barat

Penelitian ini bertujuan untuk mengetahui perbedaan pengaruh pada dimensi sibling relationship (warmth, relative power, conflict dan rivalry) terhadap kesejahteraan psikologis peserta didik SMA Negeri di Jakarta Barat. Pendekatan yang digunakan dalam penelitian ini ialah pendekatan kuantitatif dengan jenis korelasional. Sampel yaitu 356 peserta didik SMA Negeri di Jakarta Barat (132 laki-laki dan 224 perempuan), usia 15-17 tahun, memiliki saudara kandung. Penentuan sampel menggunakan teknik multistage random sampling. Pengumpulan data menggunakan angket adaptasi, Sibling Relatonship Questionnaire (SRQ) yang disusun oleh Furman dan Buhrmester (1990) sebanyak 48 item dan Scale of Psychological Well-Being (SPWB) milik Ryff (1989) sebanyak 84 item. Uji validitas menggunakan expert judgement dan uji coba instrumen dengan rumus Person’s Product Moment. Uji reliabilitas menggunakan rumus Alpha Cronbach dengan SPSS v.25, diperoleh koefisien reliabilitas SRQ sebesar 0,916 dan SPWB sebesar 0,669. Teknik analisis data menggunakan Pearson’s Product Moment dan hipotesisnya diuji dengan One-Way ANOVA menggunakan program SPSS v.25. Hasil penelitian menunjukkan bahwa dimensi warmth berpengaruh secara positif terhadap kesejahteraan psikologis peserta didik (0,178 > 0,05), dimensi relative power berpengaruh secara positif terhadap kesejahteraan psikologis peserta didik (0,109 > 0,05), dimensi conflict berpengaruh secara negatif terhadap kesejahteraan psikologis peserta didik (-0,105 > 0,05) dan dimensi rivalry memiliki pengaruh negatif terhadap kesejahteraan psikologis peserta didik (-0,114 > 0,05). Hasil uji hipotesis ANOVA menunjukkan bahwa Fhitung > Ftabel atau 4,786 > 2,39, dengan demikian sibling relationship secara keseluruhan memiliki pengaruh yang berbeda terhadap kesejahteraan psikologis peserta didik SMA Negeri di Jakarta Barat. Namun, berdasarkan hasil Pearson Correlation dibandingkan dengan tabel koefisien korelasi, didapati bahwa pengaruh yang terjadi dari masing-masing dimensi pada sibling relationship terhadap kesejahteraan psikologis peserta didik sangat rendah. Uji Tukey HSD juga menunjukkan bahwa hanya dimensi rivalry yang memiliki pengaruh berbeda dengan ketiga dimensi lainnya (warmth, relative power, conflict) terhadap kesejahteraan psikologis peserta didik SMA Negeri di Jakarta Barat.   This study aims to determine the difference in affect of dimensions of sibling relationship (warmth, relative power, conflict and rivalry) on psychological well-being in senior high school students at West Jakarta. Suggestions used in this research are quantitative with correlational type. The samples were 356 high school students at West Jakarta (132 males and 224 females), age 15-17, has sibling. Determination of the sample multistage random sampling technique. Data collected by forms of an questionnaire which adapted, that is Sibling Relationship Questionnaire (SRQ) organized by Furman and Buhrmester (1990) amount 48 items, and Scale of Psychological Well-Being (SPWB) by Ryff (1989) amount 84 items. Validity test uses expert judgement and instrument testing with the Pearson’s Product Moment. Realibility test using the Cronbach Alpha with SPSS v.25 obtained the reliability coefficient SRQ is 0,916 and SPWB is 0.669. Data analyzed using Pearson’s Product Moment and the hypothesis was tested by One-Way ANOVA with SPSS v.25. The results showed that warmth dimension had a positive effect on psychological well-being of students (0,178 > 0,05), relative power dimension had a positive effect on psychological well-being of students (0,109 > 0,05), conflict dimension had a negative effect on psychological well-being of students (- 0,105 > 0,05), and rivalry dimension had a negative effect on psychological well-being of students (-0,114 > 0,05). Hypothesis test by ANOVA results that Fcount > Ftable or 4,786 > 2,39, means sibling relationship has a different effect on psychological well-being in senior high school students at West Jakarta. However, based on the results of Pearson Correlation compared to the correlational coefficient table, was found that the effect of each diomension of sibling relationship on psychological well-being of students was very low. Tukey HSD test also shows that only rivalry dimension has a different effect from the other three dimensions (warmth, relative power, conflict) on psychlogicall well-being in senior high school students at West Jakarta.
