Definition of Terms
The following are the definitions of the terms commonly used throughout the thesis.
Validity
Validity refers to “whether an instrument measures what it was designed to measure”
(Field, 2009, p.11).
Construct validity
Construct validity refers to the extent to which an instrument measures what it purports to
measure. In other words, it is “the extent to which a measure behaves the way that the construct
it purports to measure should behave with regard to established measures of other constructs”
(DeVellis, 2003, p. 53).s study:
1. Nomophobia can be measured using a self-reported questionnaire.
2. The students are representatives of U.S. college student population at the university
where this study is conducted.
Significance of the Study
Given the dearth of research into nomophobia, this study aims at contributing to
nomophobia research literature by revealing the dimensions of nomophobia that may be further
investigated. Moreover, the development of a new nomophobia measure will be useful for
researchers interested in investigating nomophobia. In addition, through the use of a mixed

methods research design, this study will help provide guidance to other researchers in the
development of new measures to investigate the impact of technology on people’s lives
