Confirmatory factor analysis of celebrity worship, digital literacy, and nostalgia: Dataset of Indonesians

This dataset is a measurement of Celebrity Worship (CWS), Digital Literacy (DL), and Nostalgia (NA). The participants were (1) For CWS, N = 3,223 people (181 males, 3042 females; Mage = 19.64 years old; SDage = 3.13 years), (2) For DL, N = 482 people (225 males, 257 females; Mage = 25.16 years old; SDage = 8.54 years), (3) For NA, N = 658 people (140 males, 518 females; Mage = 21.26 years old; SDage = 1.93 years). The data was obtained using a survey via Google Forms in June 2018 and April–July 2020 in Indonesia. The analysis techniques were confirmatory factor analyses/CFA using LISREL and test of differences using JASP. The data could be used by the Indonesian Ministry of Communication and Informatics (KEMENKOMINFO), Indonesian Ministry of Education and Culture (KEMENDIKBUD), Indonesian Ministry of Youth and Sports (KEMENPORA), as well as social marketers to map the three constructs in Indonesian youth and to prevent the adverse effects and impacts of celebrity worship, digital illiteracy, and inappropriate mode of nostalgia.

Value of the Data
• This dataset contributes to celebrity worship mapping in Indonesia, so that certain government bodies, non-governmental organizations (NGOs), and companies that have CSR (corporate social responsibility) funds for the development of Indonesian youth can use it for educational campaigns (e.g. notices or information sheets), to prevent detrimental outcomes from extreme celebrity worship, such as physical, psychological, economic, and social losses, including losses of lives through suicide. • The presented dataset can be used as the guiding material to develop educational modules, training, algorithms, public service announcements, social movements, and other intervention programs on digital literacy for society as well as the government's leading sector of information and communication, i.e. the Indonesian Ministry of Communication and Informatics (KEMENKOMINFO). This dataset is socially significant in a period of worldwide uncontrolled information. By considering this dataset carefully, Indonesian youth can be empowered to find, evaluate, and responsibly use reliable/credible information, and to also practice basic of internet safety. • Open data on nostalgia can become an important socioemotional capital for Indonesian people and has the potential, for further insights and development of experiments, to be correlated with other psychological variables that are harmful in individual and social life by positioning nostalgia as a buffer. For laypeople, the dataset on nostalgia can function as a reflection to not be trapped in reminiscing the past, and to use it as a positive coping mechanism in managing actual adversity.

Data Description
Confirmatory factor analyses (CFA) were done on three variables, i.e. Celebrity Worship (CWS), Digital Literacy (DL), and Nostalgia (NA). A few studies indicated that CWS is negatively correlated with DL [1] , and NA is positively correlated with CWS [2] . However, this study does not aim to test the relationship between the variables, but rather to provide confirmatory factor analysis for each variable.
Factors of Celebrity Worship (CWS) are Entertainment-social (ES), Intense-personal (IP), and Borderline-pathological (BP) [3] . Factors of Digital Literacy (DL) are: to effectively search and find the necessary information (SF); to protect oneself from malicious and redundant content (PC); to verify and critically evaluate information using alternative sources of information (VI); to adequately perceive information and effectively use it (PU); to effectively and correctly disseminate  Note . Good fit criteria: RMSEA 0.08; SRMR < 0.08; CFI 0.90; AGFI > 0.90 [6] ; any three of these criteria were met.  Note. t > |1.96| = p < 0.05 (CFA Output from LISREL 8.80). SF = To effectively search and find the necessary information; PC = To protect oneself from malicious and redundant content; VI = To verify and critically evaluate information using alternative sources of information; PU = To adequately perceive information and effectively use it; CD = To effectively and correctly disseminate information; SS = Specific skills, ability to use new media, use internet-services and technical devices. information (CD); and specific skills, ability to use new media, use internet-services and technical devices (SS) [4] . Factors of Nostalgia (NA) are Positive Affect (PA), Self-regard (SR), Social Connectedness (SC), and (4) Meaning in life (ML) [5] . The Goodness of Fit Statistics of each variable are presented in Table 1 . The CFA illustrations are included in the Supplementary Materials (standardized and t values presented).
The correlation matrices between dimensions are shown in Table 2 (Celebrity Worship), Table 3 (Digital Literacy), and Table 4 (Nostalgia).  Note . ES = Entertainment-social; IP = Intense-personal. Note . SF = To effectively search and find the necessary information; PC = To protect oneself from malicious and redundant content. Note . PA = Positive affect; SR = Self-regard; SC = Social connectedness.   Table 5 (Celebrity Worship), Table 6 (Digital Literacy), and Table 7 (Nostalgia). The covariance matrix allows data validation and extension by other data miners and interpreters, and gives a chance for other possible elucidations to be examined subsequently [7] .
The correlations between age, all predictors, and criterion variables are shown in Table 8 . The test of differences based on domicile is presented in Table 9 , and descriptive statistics of the variables based on domicile is presented in Table 10 . It is shown that age correlates positively with Celebrity Worship (as a total score) and all its dimensions, but correlates negatively (although low) with Digital Literacy (as a total score). In terms of CWS and two of its dimensions (ES/Entertainment-social, IP/Intense-personal), it is shown that samples outside Java scored    higher than samples inside Java. Samples inside Java also scored higher than samples outside Java in terms of PC and PU but not Digital Literacy (as a total score).

Experimental Design, Materials and Methods
The data came from a psychometric design to assess the construct validity of Celebrity Worship, Digital Literacy, and Nostalgia. The survey methods and purposive sampling techniques were employed. Participant demographics are shown in Table 11 , and the completed instruments are shown in Table 12 . The data was analyzed with LISREL 8.80 in the form of Confirmatory Factor Analyses (CFA), correlation matrices, and covariance matrices, as well as JASP for Windows ver. 0.11.1. presented as descriptive statistics and tests of differences between domiciles. Confirmatory Factor Analysis is the appropriate method for construct validation by taking into account the relationship between latent factors and observed variables, so that it potentially reduces measurement errors and thus increases statistical accuracy [8] . Note . * The imbalance between the number of sexes is due to the majority of participants who were K-Pop Fans [9] are females. Potential re-use of this dataset is limited, i.e. more applicable to females than males.  [3] . Dimensions: • Entertainment-social (Scale no. 1-7; code: ES1 -ES7): Attraction to celebrity as one's means of entertaining and for socializing with friends. • Intense-personal (Scale no. 8-20; code: IP1 -IP13): One's intense and compulsive feeling related to a celebrity.
