Self-report measures are the most common approach to quantifying physical activity levels and patterns in free-living adult populations.\u00a0 The three main types of subjective instruments are recall questionnaires, physical activity logs, and physical activity diaries.\u00a0 Individual data obtained from self-report measures are typically converted into estimates, which allow researchers to categorize or rank individuals or populations by physical activity level.<\/p>\n[\/vc_column_text][mk_padding_divider][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_column_text title=”Physical Activity Questionnaire” disable_pattern=”false”]The physical activity questionnaire is the most practical self-report instrument in physical activity research.\u00a0 Physical activity questionnaires are subjective recall instruments that vary in detail, type of activity assessed, reference periods, administration, completion time, targeted population, and how respondents are classified.\u00a0 Due to their subjective nature, these instruments are inherently limited by factors such as recall error, social desirability or gender bias, floor effects, misinterpretation of terminology, and some questionnaires fail to quantify the totality of physical activity dimensions and contexts.\u00a0 However, a plethora of questionnaires exist and many have already been successfully tested for validity and reliability in a range of target populations.\u00a0 Some advantages to using questionnaires over other self-reporting instruments include:<\/p>\n

Activity diaries are superior to activity recall and are capable of simultaneously collecting data on many subjects at low cost. Recording frequency is determined by the investigator, and has ranged from every minute to every 4 hours, and is typically limited to 1-3 days. The detail of diary entries also varies, from meticulous records of every single activity throughout the day, to logging specific activities assigned to general categories.[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":" [vc_row fullwidth=”true” attached=”true” css=”.vc_custom_1459813899385{background-color: #81d742 !important;}”][vc_column width=”1\/6″][mk_button dimension=”flat” size=”large” url=”http:\/\/ucsdeparc.ucsd.edu\/?page_id=6443″ align=”center” fullwidth=”true” margin_bottom=”0″ bg_color=”#81d742″ btn_hover_bg=”#ffffff” btn_hover_txt_color=”#2788b0″]Tools and Platforms[\/mk_button][\/vc_column][vc_column width=”1\/6″][mk_button dimension=”flat” size=”large” url=”http:\/\/ucsdeparc.ucsd.edu\/?page_id=6453″ align=”center” fullwidth=”true” margin_bottom=”0″ bg_color=”#81d742″ btn_hover_bg=”#ffffff” text_color=”dark” btn_hover_txt_color=”#2788b0″]Subjective Measurement[\/mk_button][\/vc_column][vc_column width=”1\/6″][mk_button dimension=”flat” size=”large” url=”http:\/\/ucsdeparc.ucsd.edu\/?page_id=6459″ align=”center” fullwidth=”true” margin_bottom=”0″ bg_color=”#81d742″ btn_hover_bg=”#ffffff” btn_hover_txt_color=”#2788b0″]Objective Measurement[\/mk_button][\/vc_column][vc_column width=”1\/6″][mk_button dimension=”flat” size=”large” url=”http:\/\/ucsdeparc.ucsd.edu\/?page_id=6461″ align=”center” fullwidth=”true” margin_bottom=”0″ bg_color=”#81d742″ btn_hover_bg=”#ffffff” btn_hover_txt_color=”#2788b0″]Data Collection Tools[\/mk_button][\/vc_column][vc_column width=”1\/6″][mk_button dimension=”flat” […]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-6453","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/eparc.calit2.net\/index.php?rest_route=\/wp\/v2\/pages\/6453","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/eparc.calit2.net\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/eparc.calit2.net\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/eparc.calit2.net\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/eparc.calit2.net\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=6453"}],"version-history":[{"count":6,"href":"https:\/\/eparc.calit2.net\/index.php?rest_route=\/wp\/v2\/pages\/6453\/revisions"}],"predecessor-version":[{"id":6684,"href":"https:\/\/eparc.calit2.net\/index.php?rest_route=\/wp\/v2\/pages\/6453\/revisions\/6684"}],"wp:attachment":[{"href":"https:\/\/eparc.calit2.net\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=6453"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
