Five Love Languages (FLL) is a theory proposed by Chapman (2010) about five ways a person feel most loved. This study was based on a lack of empirical evidence supporting the construct. Therefore, it aimed to validate five love languages and the results of this study were expected to be an empirical evidence to support Chapman’s idea. A Likert scale was constructed and tested toward 400 participants (148 males, 252 females; Mage = 19.85 years, SDage= 1.51 years). The FLL scale showed a promising composite reliability score ( .884) and satisfying item-total correlations (averagely > .250). Statistical analyses showed that there were 17 valid items in the Five Love Languages Scale. Confirmatory factor analysis supported the five factors in Chapman’s initial proposal.

Driving behavior is one of the routine activities carried out by individuals on a daily basis, both with two wheeled and four wheeled vehicles. A driver who drives his vehicle can see driving activity is a complex activity. So to be able to drive safely, responsibly and have good driving ethics and behavior, one must also have certain psychological aspects to support soft skills consisting of cognitive, affective and personality. Based on this, the researcher tried to arrange a Form A Psychological Test to obtain a Driver’s License. Psychological Test Form A is administered both online and offline. The construction of the test was carried out based on three aspects of the National Police Chief Regulation No. 5 Year 2021. The items of the psychological test form A have gone through field testing with 41 participants who already have a driving license (SIM) and were selected based on the results of the content validity evaluation with expert judgment, the level of diffilcuty and discriminatory power of the item, and the reliability of each sub aspect. Psychological test form A consist of three aspect and nine sub aspects with a total of 57 items, which has a reliability coefficient of each moving between 0.639 to 0.936.

This study aims to find out the extent to which the variabels of Emotion Regulation Self awareness can predict Anxiety. The emotion regulation variabel was measured by an emotion regulation scale based on Thompson's theory (2017), a self-awareness scale based on Morin’s theory (2016) and a counseling anxiety scale based on Stuart's theory (2016). The research was conducted on the support buddy community, LISA Helpline, Bali Province with 113 research samples. The analytical method used is multiple linear regression. The results showed that the variabels of emotion regulation and self awareness can predict anxiety in support buddy.

This study aims to create a discipline measuring tool with good psychometric properties for Indonesian Air Force Military Personnel (IMPI-D32). It was conducted using an integration of self-discipline, motivation to obey, and discipline theories in a military context. The IMPI-D32 consists of 32 items and its construction are based on the Classical Theory Test. The item's content validity was estimated using the Aiken V index at a minimum of .690. Furthermore, the item discriminations showed that the corrected item-total correlation for all items is above .3. Meanwhile, the reliability estimation with the Spearman-Brown formula indicated a satisfactory coefficient value of .916. The standard error of measuring the IMPI-D32 was 3.439 with the confidence of true score interval between X-6 to X+6.
