Richardson dan Suinn (dalam Mahmood & Khatoon, 2011) mengatakan bahwa kecemasan Matematika adalah perasaan tegang dan cemas yang menggangu dan bisa menghambat kemampuan mental aritmetika dalam kehidupan sehari-hari. Bandura (dalam Feist & Feist, 2013) mendefinisikan self-efficacy sebagai keyakinan diri seseorang pada kemampuannya untuk melakukan kontrol terhadap peristiwa yang sedang mereka hadapi. Tujuan dari penelitian ini untuk mengetahui hubungan antara kecemasan Matematika dan self-efficacy dengan hasil belajar Matematika siswa SMA X di Kota Palangka Raya, Kalimantan Tengah. Peneliti menyertakan 467 siswa yang berasal dari kelas X, XI, dan XII menggunakan teknik purposive sampling. Pengambilan data dengan menggunakan kuesioner kecemasan Matematika, dan kuesioner self-efficacy serta data hasil belajar Matematika berdasarkan nilai rapot siswa. Analisis data dalam penelitian ini yaitu menggunakan teknik spearman correlation. Hasil penelitian menunjukkan terdapat hubungan signifikan negatif antara kecemasan Matematika dan hasil belajar Matematika siswa SMA (r = -0,196 dan p = 0,000 < 0,05). Hasil penelitian ini juga menunjukkan bahwa terdapat hubungan signifikan positif antara self-efficacy dengan hasil belajar Matematika siswa SMA (r = 0,210 dan p = 0,000 < 0,05).

Substance-use problems affect not just the residents in the treatment facility but the whole family system. The present study considered the family members of the residents in treatment and rehabilitation as the respondents of the study. Specifically, the study looked into the family functioning, personality type, and codependency. Codependency was measured in terms of self-sacrifice, reactivity, and external focus. Problem-solving skills, goal setting, and communication skills were used as measures of family functioning. Moreover, personality type was measured in terms of openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. There were 302 respondents in the study from different public and private treatment and rehabilitation facilities in Luzon, Visayas, and Mindanao. The result shows that problem-solving skills predict self-sacrifice with 13.6% of variance accounted for. In addition, higher level of neuroticism predicts low level of reactivity or willingness to solve their family problems and that goal setting predicts external focus. The study implies that one's perceived ability to solve family problems increases the likelihood to be selfless in handling family problems. Furthermore, worry and anxiety decreases the willingness to help family members but the goal of making their family members happy contributes to their desire to respond and prioritize their family's needs. The study strengthens and affirms the collectivistic culture and strong family ties of Filipinos.

Prokrastinasi akademik merujuk pada penundaan yang hanya terbatas pada tugas dan aktivitas yang berkaitan dengan pembelajaran. Prokrastinasi akademik dianggap sebagai permasalahan yang umum terjadi pada para pelajar. Tujuan penelitian ini adalah untuk mengetahui peran self-efficacy dan self-control terhadap prokrastinasi akademik pada siswa SMA. Penelitian ini merupakan penelitian kuantitatif non eksperimen yang menyertakan 395 siswa SMA X Tangerang dengan menggunakan teknik sampling jenuh. Instrumen yang digunakan untuk mengukur variabel adalah skala Self-Efficacy oleh Jovita yang disusun berdasarkan teori Bandura; Self-Control Scale oleh Tangney, Baumeister, dan Boone; dan skala prokrastinasi akademik yang disusun berdasarkan teori Schouwenburg. Analisis data dilakukan dengan menggunakan teknik regresi linier berganda melalui program SPSS versi 18. Hasil penelitian menunjukkan bahwa self-efficacy dan self-control memiliki peran yang signifikan secara simultan terhadap prokrastinasi akademik (F = 138.373, p = 0.000 < 0.05). Self-efficacy dan self-control secara simultan berkontribusi terhadap prokrastinasi akademik sebesar 41.4%, sedangkan 58.6% prokrastinasi akademik dipengaruhi oleh variabel lain yang tidak diteliti dalam penelitian ini. Selain itu, hasil penelitian menunjukkan bahwa self-control lebih berperan terhadap prokrastinasi akademik dibandingkan dengan self-efficacy.
