College students are using social network sites such as Facebook to communicate with their families and friends. However, empirical evidence is needed to examine whether there exists a reciprocal relationship between students' use of social network sites and their psychological well-being. The present study focused on two reciprocally-related research questions: (a) Is there an impact of loneliness on Facebook intensity and motive for using Facebook among first-year college students? (b) Is there an impact of Facebook intensity and motive for using Facebook on loneliness? Data were collected from a sample of 340 first-year college students and were analyzed through structural equation modeling. No reciprocal relationship was found in the study: Facebook intensity had a positive impact on loneliness and, motive for using Facebook did not have any impact on loneliness, whereas loneliness influenced neither Facebook intensity nor motive for using Facebook.

Contrary to the adage warning against changing test answers, mean gain from changing has been an invariant research finding. Consistency of this gain was tested for students instructed about the research results, and composition of the gain was analyzed by examining the students' reasons for changing. Students in six graduate measurement classes instructed about the answer-changing literature responded to three exams and a questionnaire. Mean gain remained positive and consistent with gain for previously studied uninstructed groups; amount of change was also stable. "Rethinking the item and conceptualizing a better answer'" was the most frequent reason given for changing. "Rereading the item and better understanding the question" was the second most cited reason, followed by "rereading/rethinking" combined, and "making a clerical error. "' For each frequently used reason, wrong-to-right (WR) changes were in the majority. Implications for research and practice are discussed.
