What factors are mentioned as increasing the risk of suicidal ideation?

The correct answer identifies that having fewer deterrents to acting on suicidal thoughts and the desire to stop the pain are significant factors that increase the risk of suicidal ideation. This highlights the psychological process involved in suicidal thinking; when individuals perceive that there are fewer barriers preventing them from acting on their thoughts, they may feel more compelled to consider suicide as a viable option. The desire to alleviate emotional or physical pain is a common motivator that can drive individuals to ideate about suicide when they believe that there are minimal obstacles stopping them from acting on such thoughts.

In contrast, other options do not align with the factors typically associated with increased risk. Less frequent thoughts or more controllable thoughts indicate a lower risk rather than a higher one, and longer durations of thoughts along with more deterrents present a paradoxical situation where additional barriers lessen the likelihood of acting on suicidal ideation. Furthermore, increased support from family and friends is instead a protective factor that generally serves to decrease the risk of suicidal ideation.
