However, social problem\u2010solving (SPS) may also be a crucial yet understudied component of these deficits. This study aimed to develop and conduct an exploratory evaluation of the Interactive Social Problem\u2010Solving Assessment for Alzheimer's Disease (ISPA\u2010AD), an experimental tool addressing the lack of instruments to evaluate SPS in AD. ISPA\u2010AD presents interactive scenarios designed to evaluate verbal and non\u2010verbal components of SPS. Forty\u2010one participants (19\u2009AD patients and 22 healthy controls) completed the task. Psychometric analyses examined internal consistency, construct validity and discriminative ability. ISPA\u2010AD showed good internal consistency (\u03b1\u2009=\u2009.811), strong construct validity and excellent accuracy in distinguishing AD participants from controls (AUC\u2009=\u2009.906). AD patients exhibited significantly lower SPS performance, revealing a specific pattern of deficits across the task dimensions. ISPA\u2010AD provides a novel, ecologically grounded approach to assessing SPS in AD. These preliminary findings support its clinical relevance and suggest that the tool may offer valuable insights into the social cognitive mechanisms underlying adaptive behaviour in AD. Further validation in larger and more diverse samples, including reliability studies, is warranted.<\/jats:p>","DOI":"10.1111\/jnp.70030","type":"journal-article","created":{"date-parts":[[2026,1,28]],"date-time":"2026-01-28T09:52:13Z","timestamp":1769593933000},"page":"361-374","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Introducing\n                    <scp>ISPA<\/scp>\n                    \u2010\n                    <scp>AD<\/scp>\n                    : Interactive social problem\u2010solving assessment for Alzheimer's disease"],"prefix":"10.1111","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-8185-1395","authenticated-orcid":false,"given":"Claire","family":"Maussire","sequence":"first","affiliation":[{"name":"Laboratory of Psychology of the Pays de la Loire, LPPL, UR 4638 Nantes University, University of Angers  Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamad","family":"El Haj","sequence":"additional","affiliation":[{"name":"Laboratory of Psychology of the Pays de la Loire, LPPL, UR 4638 Nantes University, University of Angers  Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Etienne","family":"Emmelin","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Angers  Angers France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e9r\u00e9my","family":"Besnard","sequence":"additional","affiliation":[{"name":"Laboratory of Psychology of the Pays de la Loire, LPPL, UR 4638 Nantes University, University of Angers  Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,1,28]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1684\/nrp.2020.0537"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0030250"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/13607860802224243"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.psych.59.103006.093639"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/17470210600943450"},{"key":"e_1_2_9_7_1","first-page":"1342","volume-title":"Body \u2013 language \u2013 communication: Volume 2","author":"Bitti P.
