“…Of the various online flow measures developed, the OFQ was chosen to be studied here for a number of compelling reasons, namely its: (i) theoretical correspondence with the flow construct considering elements/dimensions of challenge (OFQ Items 1, 4), merging action and awareness (OFQ Item 1), task concentration (OFQ Item 1), a sense of potential control (OFQ Item 6), loss of self-consciousness (OFQ Item 1), altered sense of time (OFQ Item 2) and autotelic experience (i.e., the joy lies within the activity it-self and not the activity's product (Items 1, 9); (ii) broadly accepted use; (iii) robust psychometric properties, (iv) brief structure (only five items, allowing it to easier incorporate in lengthier surveys); (v) distinct, yet complimentary content to other immersion/ transportation scales (i.e. it explicitly emphasizes one's engagement/immersion with what they do online, and not their virtual context or persona/avatar of representation within it in an undifferentiated manner) and; (vi) capacity to accommodate international comparisons due to its use in different cultural samples and adaptation across different languages (e.g., English, Greek, Cypriot; [10][11][12][13][22][23][24]). Despite the scale's original validation using a predominantly adult sample of internet users (61% ranged between 20-40 years [12]), later studies confirmed its validity and reliability across different age-groups and national samples.…”
