Available research findings indicate a significant positive association between loneliness and suicidal ideation and\/or behaviour. The aim of the present longitudinal study was to investigate whether loneliness at baseline (T0) is prospectively associated with suicidal ideation and\/or behaviour at follow\u2010up (T1), independent of gender, social circle, depression, anxiety, stress and prior lifetime suicidal ideation and\/or behaviour. Data were obtained via an online survey in a repeated\u2010measures design in a large German population sample (\n                    <jats:italic>N<\/jats:italic>\n                    \u2009=\u20094277; 18\u201389\u2009years of age), divided into four age groups (18\u201329, 30\u201345, 46\u201365 and 66\u201389\u2009years). In order to examine the association between loneliness and suicidal ideation and\/or behaviour, three\u2010step hierarchical regression analyses were conducted in each age group, respectively. The regression models explained between 25.2% and 39.3% of the variance in T1\u2010suicidal ideation and\/or behaviour. Loneliness proved to be significantly associated with T1\u2010suicidal ideation and\/or behaviour, beyond affective symptoms, social circle and previous suicidal ideation and\/or behaviour. The results underscore the importance of loneliness as a relevant component of suicidal ideation and\/or behaviour in the German population. The findings emphasise the need to address loneliness in suicide risk assessment.\n
