How do I make best use of survivors with the 'Counseling' personal skill?

• How do I quickly level up the 'Counseling' skill, if it's possible to level it up?
• What kinds of missions or activity should I have them undertake?
• Will it better improve a low morale (angry, sad, depressed, etc.) survivor's mood or attitude if I play as a survivor with the 'Counselling' skill on 'Take (survivor) out to walk' missions?
• Or should these survivors stay at home to improve community morale? (Will their 'Counseling' skill still increase?)

According to the State of Decay Wikia, the only level-able skills are those you use while exploring/combating.

• Cardio (Improve by sprinting)
• Wits (Improve by searching, completing certain missions)
• Fighting (Improve by killing zombies in melee)
• Shooting (Improve by killing zombies with guns)
• Leadership (Improve by fighting, completing certain missions)
• Powerhouse (Improve by fighting)
• Reflexes (Improve by fighting)

All other skills cannot be improved and only affect homebase. People with Counseling skills reduce the frequency of morale-related problems at home (angry/sad/etc).

Also, according to the Wikia, Counseling has no effect on the outcome of the Fear/Anger Management missions, but Leadership does.
