This study aims to examine the associations between social support/strain and cognitive outcomes. </p> </div><div class="section"> <a class="named-anchor" id="d10251634e211"> <!-- named anchor --> </a> <h5 class="section-title" id="d10251634e212">Methods:</h5> <p id="d10251634e214">Data were drawn from the Population-Based Study of Chinese Elderly ( <i>N</i> = 3,159). Cognitive function was measured by a battery of tests including the East Boston Memory Test, the Digit Span Backwards assessment, and the Symbol Digit Modalities Test. Social support and strain were measured by the scales drawn from the Health and Retirement study. Multiple regression analyses were conducted. </p> </div><div class="section"> <a class="named-anchor" id="d10251634e219"> <!-- named anchor --> </a> <h5 class="section-title" id="d10251634e220">Results:</h5> <p id="d10251634e222">Social support was significantly associated with global cognitive function (β = .11, <i>SE</i> = .02, <i>p</i> &lt; .001), episodic memory (β = .11, <i>SE</i> = .03, <i>p</i> &lt; .001), working memory (β = .18, <i>SE</i> = .08, <i>p</i> &lt; .05), and executive function (β = 1.44, <i>SE</i> = .37, <i>p</i> &lt; .001). Social strain was significantly associated with global cognitive function (β = .23, <i>SE</i> = .05, <i>p</i> &lt; .001), episodic memory (β = .27, <i>SE</i> = .07, <i>p</i> &lt; .001), working memory (β = .34, <i>SE</i> = .17, <i>p</i> &lt; .05), and executive function (β = 2.75, <i>SE</i> = .85, <i>p</i> &lt; .01). In terms of sources of social support/strain, higher support from friends was significantly associated with higher global cognitive function (β = .04, <i>SE</i> = .02, <i>p</i> &lt; .05), higher episodic memory (β = .05, <i>SE</i> = .02, <i>p</i> &lt; .05), and higher executive function (β = .71, <i>SE</i> = .29, <i>p</i> &lt; .05). Higher strain from spouse was significantly associated with higher global cognitive function (β = .10, <i>SE</i> = .03, <i>p</i> &lt; .01), higher episodic memory (β = .11, <i>SE</i> = .04, <i>p</i> &lt; .01), and higher executive function (β = 1.28, <i>SE</i> = .49, <i>p</i> &lt; .01). Higher strain from friends was significantly associated with higher executive function (β = 3.59, <i>SE</i> = 1.17, <i>p</i> &lt; .01). </p> </div><div class="section"> <a class="named-anchor" id="d10251634e319"> <!-- named anchor --> </a> <h5 class="section-title" id="d10251634e320">Conclusions:</h5> <p id="d10251634e322">Social support and strain were associated with cognitive outcomes.
